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.

If all parameters are empty, implementations should return early instead of deleting everything by accident.

Implementation
