Bug fixes and log statements
Also shims next nonce code with a fine-for-now piece of code which is unviable
in production, yet should survive testnet.

Add a LibP2P instantiation to coordinator
It's largely unoptimized, and not yet exclusive to validators, yet has basic
sanity (using message content for ID instead of sender + index).

Fixes bugs as found. Notably, we used a time in milliseconds where the
Tributary expected  seconds.

Also has Tributary::new jump to the presumed round number. This reduces slashes
when starting new chains (whose times will be before the current time) and was
the only way I was able to observe successful confirmations given current
surrounding infrastructure.

Test the Coordinator emits KeyGen
Mainly just a test that the full stack is properly set up and we've hit basic
functioning for further testing.

Replace "coin" with "network"
The Processor's coins folder referred to the networks it could process, as did
its Coin trait. This, and other similar cases throughout the codebase, have now
been corrected.

Also corrects dated documentation for a key pair is confirmed under the
validator-sets pallet.

Consolidate RockDB code
Moves explicitly to zstd. RockDB recommends zstd, or at least lz4 over snappy,
and this minimizes which dependencies we pull in.

Update how RPCs are handled
The processor now takes three vars and joins them itself. message-queue uses a
single argument, with defaults, as it's a service we control.

Update the flow for completed signing processes
Now, an on-chain transaction exists. This resolves some ambiguities and
provides greater coordination.

Remove TODO about code de-duplication
It's infeasible to write a macro/function there. Does add a type alias which
makes things cleaner.

Spawn a new async task for each block message
This probably should be done with n-long lived tasks, one per Tributary. While
this may not be suitably performant long-term (potential DoS vector), this at
least resolves the halting concerns.

Publish ExternablBlock/SubstrateBlock, delay *Preprocess until ID acknowledged

acknowledged.

Add a TributaryReader which doesn't require a borrow to operate
Reduces lock contention.

Additionally changes block_key to include the genesis. While not technically
needed, the lack of genesis introduced a side effect where any Tributary on the
the database could return the block of any other Tributary. While that wasn't a
security issue, returning it suggested it was on-chain when it wasn't. This may
have been usable to create issues.

Start handling P2P messages
This defines the tart of a very complex series of locks I'm really unhappy
with. At the same time, there's not immediately a better solution. This also
should work without issue.

Reload Tributaries
add_active_tributary writes the spec to disk before it returns, so even if the
VecDeque it pushes to isn't popped, the tributary will still be loaded on boot.

Handle adding new Tributaries
Removes last_block as an argument from Tendermint. It now loads from the DB as
needed. While slightly less performant, it's easiest and should be fine.

Add a test to the coordinator for running a Tributary
Impls a LocalP2p for testing.

Moves rebroadcasting into Tendermint, since it's what knows if a message is
fully valid + original.

Removes TributarySpec::validators() HashMap, as its non-determinism caused
different instances to have different round robin schedules. It was already
prior moved to a Vec for this issue, so I'm unsure why this remnant existed.

Also renames the GH no-std workflow from the prior commit.
