This PR brings some optimisations for the zkapp generators used by tests and the batch transaction tool. In particular:

we don't use an on-disk ledger, avoiding disk IO entirely
we batch the writes for ledger initialisation, dramatically speeding up that part of the code.

On my machine, this brings the runtime of the test in src/lib/staged_ledger/tests down from 528s to 247s, a roughly 115% speed-up.
