Instead of using normal sync, we should be able to use for example Geth, sync with Hoodi, and export all blocks from genesis to head to some rlp file, like hoodi-blocks.rlp. I think Geth has this capability.

Then, on an empty database, we should be able to import them to ethrex via ethrex import hoodi-blocks.rlp.

This should be much faster and should have several benefits:

• Easier performance benchmarks, charts, etc..
• Easier debugging of levm

This was inspired on https://github.com/jsvisa/goleveldb-bench/blob/pebble/pebble-2.md#geths-workflow

Acceptance criteria:

• Do not import blocks in batch, we want to verify the root on each block
• Support very large .rlp files. Do we want/nned to stream the file?
• If a block is invalid, we probably want to output an error message and exit.
