Hotkeys for audio labeling

There is a new hotkey available for pausing and starting audio: ctrl+p (Windows) or command+p (Mac). This is in addition to the space hotkey that performs the same function. However, this new hotkey is useful when you are working with audio and have a text area field in focus.

Video frame classification template

The video frame classification template is now available in the Label Studio app as well as the documentation.

Performance improvements

Optimized the API calls made from the frontend within the members management and Data Manager users lists. Also optimized the Projects page for faster load times.
