feat(types): introduce state diff record type and compression (#194)

# What ❔

Introduces the `StateDiffRecord` type and advanced compression for this
type.

## Why ❔

In boojum, all storage writes will be replaced with `StateDiffRecord`
types. In order to cut down on the number of bytes published to L1 we
want to compress this data as much as possible.
