Add optional prover parameters file path to the adapted Stwo CLI

[m-kus]

Similarly to Stone which had prover config and parameters files, this PR introduces an optional cmd argument pointing to the params file.

The expected format is the following:

{
    "channel_hash": "blake2s",
    "pcs_config": {
        "pow_bits": 24,
        "fri_config": {
            "log_last_layer_degree_bound": 0,
            "log_blowup_factor": 2,
            "n_queries": 36
        }
    }
}

If the file is not specified, the defaults are set to ensure 96 bits of security.

@ohad-starkware can you please take a look? 🙏

[ohad-starkware]

this needs to be 3-4 separate prs,

1. bump stwo
2. hash type in the cli
3. pcs config in the proof
   4.default parameters

I believe this is under @yuvalsw jurisdiction

Ok thanks, I'll split into several PRs!
Note that (1) would result in cairo-serialize build error, so maybe (1) + (3) is ok?

[ohad-starkware]

yes, u decide
