Incomplete color normalization

[levibuzolic]

Description

The new color normalization added in #50 has broken react-native-web shadow styling for some colour formats.

react-native-unistyles/src/utils/normalizer.ts

Lines 11 to 13 in 8653436

	// for now supports
	// hex colors (3, 6, 8) chars
	// colors like orange red etc.

Based on the comments in the commit it looks like it's known that it's an incomplete implementation.

I imagine to stay in-sync with what React Native itself supports, it'd make sense to add a peerDependency to @react-native/normalize-colors which is the underlying utility library that React Native uses to pre-parse colours and then mix-in the alpha channel where required.

I'd be happy to create a PR with that implementation if that approach is suitable.

Steps to reproduce

1. Use a shadowColor of black with an opacity of 0.5
2. Observe output colour is black without opacity

I wasn't aware of that! I also didn't know about this lib. I will happily accept the PR 🙏
