Unknown color when parsing 3 character hex string

[DRFR0ST]

Hi there! I've arrived here to report an issue with colors passed to the RNTooltips component.

Context

I've tried to apply a hex color to tintColor and textColor. It worked very well for regular 6 character hex color like: #000000 and #FFFFFF. But in my case, I wanted to pass it the colors generated from my theme and one of them (provided to tintColor) was a 3 character hex color: #fff which then threw an error saying Unknown color.

Process

1. Do the setup described in docs.
2. Pass tintColor a 3 character hex string (eg. #fff).
3. It should throw error on mount.

Expected result

It should parse the 3 character hex string same as the 6 character hex.

Current result

Not being able to pass a 3 character hex string.

Possible Fix

• Parse the hex color on JS side, before passing it to Tooltips.Show. https://github.com/prscX/react-native-tooltips/blob/master/RNTooltips.js#L144
• Parse the hex color on Native side, before passint it to Color.parseColor. https://github.com/prscX/react-native-tooltips/blob/master/android/src/main/java/px/tooltips/RNTooltipsModule.java#L102

Maybe this article will be helpful.

I might not find time to make a pull request but I would be happy to help, if you need any.

PS. Since I'm already here, a feature request: Please make the package TypeScript compatible, it was a thing that annoyed me a little. 😃
