Custom (external) typeface

Feature description:

I would like to suggest support to custom typeface, to import external ttf/otf fonts to use on the app.

Problem solved:

No problem

Brought benefits:

User experience, more customization means more satisfaction.

Other application solutions:

Only app I know with this feature is BlackPlayer, we can place fonts in the app folder named properly and the app reads it.

Additional description and context:



Screenshots / Mockup:



This is not possible with current state of Compose and with all the blocking of file access will probably never be possible.

With that said I can add a couple more font from Google Font.
