feat: add toolkit for exporting and transforming missing block header fields and fix blockhash mismatch (#903) 
* feat: add toolkit for exporting and transforming missing block headers fields

* feat: add missing header writer to write the missing header file with deduplicated headers

* feat: add sha256 checksum generation

* add bitmask to encapsulate logic around header information in it. also add vanity count as part of the bitmask

* feat: add optional verification of input and output file with separate csv file

* add feature to continue already existing header file

* change byte layout of deduplicated file due to too many vanities (>64) in Sepolia data

* fix some stuff

* add state root to header

* goimports

* only create 1 task at a time

* address review comments

* add optional coinbase and nonce to missing header

* add flag to run fetch from rollup relayer DB

* go mod tidy

* fix(l1 follower, rollup verifier): blockhash mismatch (#1192)

* implement missing header fields reader and manager

* chore: auto version bump [bot]

* increase download timeout

* sanitize BaseFee when executing blocks from DA

* initialize and pass missing header manager to DA syncing pipeline

* add state root to deduplicated header

* overwrite state root if given via missing header file

* fix test

* set correct links and missing header file hashes

* allow reading of previous headers by resetting file and buffer to support reset of syncing pipeline

* address review comments

* add coinbase and nonce field to missing header reader

* replace missing header reader in toolkit with actual implementation

* update sync from DA pipeline to include coinbase and nonce from missing header fields file

* update sha256 hashes for missing header fields files

* lint

* address review comments

* address review comments

* chore: auto version bump [bot]
