* Deribit: Switch to string IDs
Switch from int to string IDs so we can use UUID.v7 instead of (the only) local high precision message id implementation
* Deribit: Dedup wsResponse / wsResponse
* Deribit: Use uuid v7 for IDs
This moves away from centralising message ids.
There's no real benefit to moving them to a central generator, since we
can one-line it, and reduce our testing plane and complexity.
And it's more concise for exchanges to say "I'm using this UUID".

* Websocket: Break out all subscription methods into subscriptions.go
* Websocket: Move connection type into its file

* Websocket: Move manager types into manager
* Websocket: Move ConnectionWrapper into manager
* Websocket: Move websocket_test to manager_test

* Websocket: Fix duplicate import of gws
* Websocket: Fix gofumpt -extra

* Kraken: Remove unused sub conf consts
These were replaced by the generic Levels and Depth fields on all subs
* Websocket: Privitise ConnectioWrapper fields
* Websocket: inline single use var WebsocketNotAuthenticatedUsingRest
* Websocket: Move documentation to template
* Bithumb: Assertify TestWsHandleData
Thusfar ExpandTemplates had only been called internally.
All methods consumers might want to get, in this case GetPairFormat,
need to be in the interface we're passing out, otherwise users can't
call them (or things that use them, like ExpandTemplates)
* Subscriptions: Add List.AssetPairs
* Subscriptions: Add Template and QualifiedChannel
These fields separate the concept of what the channel is from the

* Websocket: Use ErrSubscribedAlready
instead of errChannelAlreadySubscribed
* Subscriptions: Replace Pair with Pairs
Given that some subscriptions have multiple pairs, support that as the
standard.
* Docs: Update subscriptions in add new exch
* RPC: Update Subscription Pairs
* Linter: Disable testifylint.Len

* Websocket: Add suffix to state consts

* Subscriptions: Fix GetKey test
* Subscriptions: Test coverage improvements
* Websocket: Change State on Add/Remove
* Subscriptions: Improve error context
* Subscriptions: Fix Enable: false subs not ignored
* Bitfinex: Fix WsAuth test failing on DataHandler
DataHandler is eaten by dataMonitor now, so we need to use ToRoutine
* Deribit: Subscription Pairs support
* Websocket: Accept nil lists for checkSubscriptions
If the user passes in a nil (implicitly empty) list, we would not panic.
Therefore the burden of correctness about that data lies with them.
The list of subscriptions is empty, and that's okay, and possibly
convenient
* Websocket: Add context to NilPointer errors
* Subscriptions: Add context to nil errors
* Exchange: Fix error expectations in UnsubToWSChans
* Shift wrapper function GetDefaultConfig to exchange.Base method definition, to ensure set defaults doesn't get called twice and to reduce code
* rm alphapoint bootstrap method as is defined as exchange.Base method
* add tests
* glorious: make it a function and make it IBOTEXCHANGE

* Exchanges: Remove Pair upgrade handling
Now redundant behind #1401. These paths should never be met.
Several legacy coin upgrade paths being deprecated as well: ZUSD and CNY
Expecting any users with bad config from 3+ years ago would have to
reset anyway.
Also: At the time the intention of this was to upgrade the config
format.
However now, instead, it'd mostly serve to reset enabled pairs if
there's a config mistake, which doesn't feel right.
* Kraken: Fix typo in Kraken type struct
* Exchanges: Abstract exchange Start() and Run()
* Exchanges: Add test for abstracted Start
* Exchanges: Move Start to Bootstrap
* Simplify waitgroup usage
* Add call to exchange.Bootstrap to allow overide or supplementation
* Exchanges: Concurrent common bootstap actions
* Gateio: Remove incorrect Run in test
* GateIO: Fix pair dependencies in tests
This ensures that the pairs are initialised no more than needed and
kind-of just-in-time.
Better pattern might be to use a function to get these pairs when we
need them.
* Exchanges: Complete UpdatePairs before ExecLims
If we're going to update pairs, it needs to complete before we check for
limits to avoid errors on old pairs
* Exchanges: Remove Start and Run from tmpl
Since they're replaced by bootstrap now and shouldn't need customisation
normally
* Alphapoint: Move Start to Bootstrap
* GateIO: Fix linter shadow var
* Websockets: Move Subscription to its own package
This allows the small type to be imported from both `config` and from
`stream` without an import cycle, so we don't have to repeat ourselves
* Subs: Renamed Currency to Pair
This was being mis-used through much of the code, and since we're
already touching everything, we might as well fix it
* Websockets: Add Subscription configuration
* Binance: Add subscription configuration
* Kucoin: Subscription configuration
* Simplify GenerateDefaultSubs
* Improve TestGenSubs coverage
* Test Candle Sub generation
* Support Candle intervals
* Full responsibility for formatting Channel name on GenerateDefaultSubs
OR consumer of Subscribe
* Simplify generatePayloads as a result
* Fix test coverage of asset types in processMarketSnapshot
* Exchanges: Abstract ParallelChanOp
* Tests: Generic ws mock instances
* Kucoin: Fix intermittent conflict in test currs
Use isolated test instance for `TestGetOpenInterest`.
`TestGetOpenInterest` would occassionally change pairs before
GenerateDefault Subs.
* adds open interest to exchanges
* ADDS TESTING YEAH
