Payment channel implementation sketch

Simplifications:

• unidirectional paychans
• no top ups or partial withdrawals (only opening and closing)

TODO

• in code TODOs
• Tidy up - method descriptions, heading comments, remove uneccessary comments, README/docs
• Find a better name for Queue - clarify distinction between int slice and abstract queue concept
• write some sort of integration test
• find nicer name for payout
• add Gas usage
• add tags (return channel id on creation)
• refactor cmds to be able to test them, then test them
• use custom errors instead of using sdk.ErrInternal
• split off signatures from update as with txs/msgs - testing easier, code easier to use, doesn't store sigs unecessarily on chain
• consider removing pubKey from UpdateSignature - instead let channel module access accountMapper
• remove printout from tests when app initialised
• refactor queue into one object
