feat: add skia as a renderer (creating abstracting package for canvases)

[BenJeau]

Changes

• Created @benjeau/react-native-draw-core utilities package for both renderers
• Moved @benjeau/react-native-draw to @benjeau/react-native-draw-svg
• Created @benjeau/react-native-draw-skia
• Renamed packages folder (removed react-native-draw- prefix)
• Added addPaths() and setPaths() ref functions

Things Left

• Have READMEs for all packages and create a new one for the root of the repo
• Document new props
• Add examples for the new props
• Add examples for the new Skia renderer
• Make the Skia renderer properly handle the multiple paths within a single PathType (honestly debating if I should simply remove that feature)
• Make sure that the grouping of the paths based on its props (color, thickness, opacity, filled, cap, join) is properly done

closes #38
closes #51
kinda closes #20 (there must be a better OR I do the same thing I do in Skia but within the SVG renderer)

Screenshots (optional)

Update - What is blocking me on this PR is the example. Since react-native-skia does not support expo at the moment, I've ported the code to a native react-native project, but I am getting some weird compilation errors on Android and iOS related to react-native-skia
