This is a refactor of expo-pixi package.

It fixes several issues, noticeably:

• Locks in the latests compatible versions of pixi.js and pixi-filters:
  • Fixes Unable to resolve module @pixi/core  #158;
• Fixes peer dependencies of expo-asset and expo-gl:
  • Fixes Incompatible with Expo 43 #221
  • Fixes To make it compatible with expo SDK 44 #222
  • Fixes Outdated expo-gl peer-dependency #156
  • Fixes Unable to resolve module expo-asset-utils #61 (expo-asset-utils is no longer needed)
• Fixes loading assets on production & fixes assets URLs on Android:
  • Fixes Error: Expected URL scheme 'http' or 'https' but was 'file' #103
  • Fixes image is not displayed after build in Expo #92
  • Fixes standalone application crashes with Invalid pixel data argument for gl.texImage2d() #66

Additionally, it adds a few features:

• TypeScript support:
  • Fixes Typescript Definition File #145
• Up-to-date examples:
  • Fixes Asset not loading for Sprite Sheet animation #136
  • Fixes Comprehensive Example: Unable to resolve "../../assets/pixi/dragon.atlas" #86
  • Fixes Can't get example to work #53
• Adds support for Web (every example is working on both mobile & web):
  • Fixes expo web support would be great #72
• Removes side-effects by just exporting PIXI instead of messing with the global scope;
• Built with expo-module-scripts;

Breaking changes:

• It removes Spine, Signature, Sketch and FilterImage. I think it's reasonable for expo-pixi to just add support for pixi.js in Expo and do nothing more. Removed components can be easily reexported to their own packages to prevent the bloating of expo-pixi package. Removing this bloat will also close a lot of issues.
