feat: stdio parallel proving

[atanmarko]

• Updated rpc tool to easily extract multiple blocks from jerigon
• simple_test.sh -> prove_stdio.sh
• prove_blocks.sh -> prove_jerigon.sh
• Added json witness files to tools/artifacts
• Add parallel proving for stdio usecase

Resolves #105
Resolves #107

Now the following can be done:

1. Extract multi block witness from jerigon node and dump it to file

cargo run --bin rpc -- fetch --start-block 1 --end-block 5 --rpc-url http://127.0.0.1:8546 | jq > witness_b1_b5.json

2. Generate proof from witness json file input and verify it

./tools/prove_stdio.sh witness_b1_b5.json

Overall LGTM, just having one question regarding the use of Option. Related to this point actually, I wonder if we don't want the stdio mode to also have the keep_intermediate_proofs argument, which currently is a jerigon specific one.

@Nashtare Lets first merge #106, as stdio parrallel proving and discarding intermediate proofs are two separate features I would say :)

Also minor nit, but I ran the tools/prove_stdio.sh script in test_only mode and the display is a bit off: (the first line being the last line of the concatenation of all the proofs being printed to stdout).

We may want to have the print be done at the outer prove function.
