Pubdata compression

[koloz193]

What ❔

Edit the compression algorithm used for state diffs. The prior one was used to make sure the system worked with the old format but this upgrade will allow us to have ~70% gain in data compression.

Change how state diffs are processed at the end of the batch.

• L1Messenger is updated to parse out the new format/values
• Compressor is updated to properly compare the encoded state diffs vs the new compressed state diffs

Why ❔

While the current iteration of compression works, we can achieve further compression with this new algorithm bringing down the amount of data needed and thus costs due to pubdata publishing.
