[WIP] feat: curio c1go: Pure Go vanilla challenge generation

[magik6k]

Related Issues

Proposed Changes

Implement a pure-Go version of Commit1, for now just supporting basic interactive PoRep.

The main goal is to get much better feedback from the code when things break so that Curio knows which parts of data appear to be corrupted.

Also makes debugging issues with sealing much, much easier.

Additional Info

Extremely WIP, 80% of the code is not here yet. Shouldn't be hard to implement, but it's also not a big priority, so it's probably only going to move forward when I get really annoyed at the rust impl.
