Commit Message

Add combined event filters for fetching multiple events in one request

Introduce Ethers.CombinedEventFilter, created via Ethers.EventFilter.combine/1
or the generated EventFilters.all/0 function of contract modules. The combined
topic_0 values are sent as an OR-ed list so filtering happens server side, and
fetched logs are decoded with their matching event selector. Works with both
Ethers.get_logs/2 and Ethers.batch/2.

Combining validates that all filters use wildcard indexed arguments and have
no conflicting default addresses (eth_getLogs accepts a single address).

Also normalize from_block/to_block keys to fromBlock/toBlock in get_logs
pre-processing, fixing batched get_logs requests with block ranges which
bypassed Ethereumex's key normalization.
