Format text custom function

For @zachmullen

is this still too locked down? Should you be able to edit the styling at the same time if you want to edit the text? Text size, color and other options are still dependent on the type specified. I don't know the immediacy of this or the intended usage, but just wondering if we should give some more control besides just formatting the TextData output.

You'd have to "coordinate" with the typeStyling properties, which I think is reasonable given that's how everything else works.

This is already much more than Zach needs, so I'm reluctant to go out of my way to make this ultra-flexible without a use case. This was just the most convenient way to expose the functions he needed.

Testing worked well.

I'm open to any ideas you may have about multiple text items per FrameDataTrack. I just don't want to have to break or change this functionality afterwards to solve a VIAME issue.
