feat(reorg_detector): compare miniblock hashes for reorg detection #236

Merged

What ❔

This PR adds logic to compare the L2 miniblock hashes to reorg_detector logic.

Why ❔

Currently reorg_detector only considers the L1 batches and their root hashes which
in case of a reorg on the miniblock level leaves such reorg undetected and nodes stuck.
