Payment channel implementation sketch

Simplifications:

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

TODO

• chnge module name to "channel"?
• Find a better name for Queue - clarify distinction between int slice and abstract queue concept
• refactor queue into one object
• Do all the small functions need to be methods on the keeper or can they just be floating around?
• Tidy up - standardise var names, method descriptions, heading comments
• any problem in signing your own address?
• Gas
• find nicer name for payout
• tags - return channel id
• create custom errors instead of using sdk.ErrInternal
• maybe 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
