* drop common uuid v4 func and imported package as needed
* removed common functions regarding json marshal and unmarshal and used the json package directly. WRT unmarshal it was calling reflect and converted to string which is also checked in the JSON package so it was doing a double up, this will be a tiny gain as it was directly used in the requester package for all our outbound requests.
* add in string
* explicitly throw away return error value
* atleast return the error that websocket initialise returns
* return error when not connected
* fix comment
* Adds comments
* move package declarations
* drop append whenever we call supported
* remove unused import
* Change incorrect spelling
* fix tests
* fix go import issue
* Attempts to update orderbook so it doesn't need to sort
* Reverts the ws ob stuff. Gets rid of sorting because it happens later. Adds some exchange features

* Who can forget good old alphapoint?
* Adds btcmarksets websocket :glitch_crab: fixes alphapoint features
* Adds extra data not in the documentation :/
* Replaces websocket features by using protocol features. However, it breaks it due to import cycles. I'm not sure what I'll do just yet
* Removes import cycle via duplicate structs.
* Increases coverage of config with `TestCheckCurrencyConfigValues`. Moves all currency pair package types into their own files or places it at the bottom of files if necessary
* Increase coverage in code.go
* One way of determining a test has failed, is when to it fails. Removed redundant explanation
* Increases code coverage of conversion
* Lint fixes
* Fixes orderbook tests
* Re-adds sorting because its important to still have the internal pre-processed orderbook to be representative of a real orderbook
* Secret lints that did not show up via Windows linting
* Adds protocol package to contain exchange features
* Fixes protocol implementation

* imports and casing
* Fixes two more nil error checks
