removeEvents method

@override Future<void> removeEvents({ List<String>? ids, List<String>? pubKeys, List<int>? kinds, Map<String, List<String>>? tags, int? since, int? until, })

Remove events from cache with flexible filtering
ids - list of event ids
pubKeys - list of authors pubKeys
kinds - list of kinds
tags - map of tags (e.g. {'p': 'pubkey1', 'e': 'eventid1'})
since - timestamp
until - timestamp
If all parameters are empty, returns early (doesn't delete everything)
