Show Date when scrolling

### Your use case

#### What would you like to do?
It would be great if element X shows the date of the messages while scrolling.

#### Why would you like to do it?
currently it's almost impossible to know when messages were sent in large groups.

#### How would you like to achieve it?
In similar style to other apps like telegram.

Schildi chat next already does this, it shouldn't be too difficult to just merge the patch back to element X.
