Gareth Kirwan b4e45e9a1b Websocket: Restructure files and types (#1859)
* Websocket: Rename stream package

* Websocket: Rename Websocket to Manager

* Websocket: Replace explicit errs with common.NilGuard

* Websocket: Move websocket_types.go to types.go

* Websocket: Minor field comment and alignment in types

* Webosocket: Rename WebsocketConnection to Connection

* Alphapoint: Make gorilla ws import explicit

Just to avoid confusion with our own packages.

* Websocket: Move stream_match to match

* Websocket: Move websocket_connection to connection

* Websocket: Move websocket.go to manager.go

* Websocket: Break out all subscription methods into subscriptions.go

* Websocket: Move connection type into its file

* Websocket: Remove PositionUpdated

Type is not used anywhere

* Kraken: Use local constant for pong

Was the only use of websocket.Pong and doesn't really feel right to
represent kraken's api resp in one of our packages

* Websocket: Move connection sub-types to connection package

* Websocket: Move manager types into manager

* Websocket: Move ConnectionWrapper into manager

* Websocket: Move websocket_test to manager_test

* Websocket: Privatise connectionWrapper

* Websocket: Remaining types into types.go

These really belong somewhere else mostly, but this will do for now

* Websocket: Tidy up connection method vars

* Gofumpt: Moving package imports around

* Websocket: Rename errDuplicateConnectionSetup

* Websocket: Fix duplicate import of gws

* Websocket: Fix gofumpt -extra

* Websocket: Standardise import of gws across other pkgs

* 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
