WIP: Add search functionality to MDPersistentSearch

API:

 MDPersistentSearch(results=[{"title": "Test", "info": "More info", "callback": """print("hello")'"""}]).open()

title: First line/headline of result

info: Second line of result

callback: The callback to be executed on_release

To add to the results simply add another dictionary to the list

TODO:

• Basic search functionality

• Error handling

• Animations (no sharp jump into the search)

• Better highlighting of searched word in results (currently very faint)

  Better look/ui:

  • Better background
  • Cards for the list

  Possible additions:

  • Toolbar that switches to a search bar Will possibly come in a future merge request
