When running the import, currently blocks are loaded in batches into a
`seq` then passed to the importer as such.
In reality, blocks are still processed one by one, so the batching does
not offer any performance advantage. It does however require that the
client wastes memory, up to several GB, on the block sequence while
they're waiting to be processed.
This PR introduces a persister that accepts these potentially large
blocks one by one and at the same time removes a number of redundant /
unnecessary copies, assignments and resets that were slowing down the
import process in general.
* blocks can be bigger than the default 1mb when json-rpc-encoded - this
happens on sepolia for example
* json-rpc bump improves debug logging and fixes a number of bugs
* json-serialization bump fixes a crash on invalid arrays in json data
At some point, it would probably be better to compute the maximum block
size from actual block constraints, though this is somewhat tricky and
depends on gas limits etc. Until then, 16mb should be plenty.
With this, sepolia can be synced :)
