Re-implementation of Local Resource Conservation in Rust: rust-lrc

[PurpleTimez]

Re-implemented Local Resource Conservation in Rust with all the interfaces and components, new code is slightly unit tested and error handling is more than summary for now: https://github.com/PurpleTimez/rust-lrc

Understanding that LRC is testing code only and that the interfaces will change heavily with the progress of the protocol. I still have 2 observations so far.

Firstly, should all internal opportunity_cost math be done in f64 or float64, like floating arithmetic can be cumbersome to handle and I'm not sure it has a real impact on reputation-based jamming handling ?

Secondly, all the resolution period and block_time, I think LocalResourceManager internal interface would gain to be defined with a block hash and timestamp, that way the opportunity_cost can be adapted to the real difficulty period ?

I'll see to integrate rust-lrc in the rust-lightning sample to test this further, and I think I still have a branch somewhere trying to add rust-lightning support in sim-ln. I won't have that much time to make progress on that during the coming weeks, though I
don't forget go back to it.
