HayesGordon 04d3908f57 Flutter release 0.13.5
Tested out the latest rive-common that now uses `package:web` and `dart:js_interop`

The `RiveFile.initializeText` and everything associated with it are deprecated. Instead, use `RiveFile.initialize`, which will always need to be called when initializing text, audio, and layout.

Calling it `initializeText` is confusing to users as they may not be using text, but still need to call this manually when using RiveFile.import.

There is maybe additional cleanup we could do here, but at least want to make sure the public API is not confusing.
