Split the repository archive by match_type, chain and first byte.

Let's implement what discussed in #1668

Revise the repository archive generation script to generate multiple zips with the format “match_type.chain.first_byte.zip” (e.g., “full_match.1.00.zip” will contain all mainnet full_match contracts with the address starting with 00).

The file system content of the archive must be identical to the repository (./match_type/chain/address/files), ensuring that decompressing all the archives in the same directory will suffice to reconstruct the repository without any additional actions.
