feat: new group consistency algorithm

This implements new group consistency algorithm described in
<https://github.com/deltachat/deltachat-core-rust/issues/6401>

New `Chat-Group-Member-Timestamps` header is added
to send timestamps of member additions and removals.
Member is part of the chat if its addition timestamp
is greater or equal to the removal timestamp.
