Add resuming options

[freyacodes]

Adds the ability to control whether Lavalink should try to resume the connection. Also adds the ability to define a session ID from a previous client connection.

This has not been tested yet, hence the draft status

I'd consider that a success

[10:10:28] [ DEBUG] [OkHttp http://localhost:2334/...] [] [LavalinkSocket] -> {"op":"ready","resumed":true,"sessionId":"z4h1g9silghmoove"}
[10:10:28] [ INFO ] [OkHttp http://localhost:2333/...] [] [LavalinkSocket] local has been connected!
