espresso/bindings: add regenerated BatchAuthenticator Go bindings

Regenerated against PR #443's BatchAuthenticator.sol via forge build +
abigen. Includes the new history-based API (espressoBatcherAt,
espressoBatcherAtBlock, espressoBatcherHistoryLength, setEspressoBatcher)
and the EspressoBatcherUpdated(address,address,uint64) event with the
fromBlock parameter; drops the removed paused() function.

Consumed by the fallback batcher (next commit) to read activeIsEspresso
and pack authenticateBatchInfo calldata. The TEE batcher in a follow-up
PR will use the same binding.
