Allow customising the badge

[1987cr]

At the moment Im changing the color and the position (only for Android) through a patch with:

Android

badge.backgroundColor = Color.parseColor("#F37468")
badge.horizontalOffset = 10

iOS

itemAppearance.normal.badgeBackgroundColor = UIColor(red: 0.953, green: 0.455, blue: 0.408, alpha: 1.0)

Feel like it's something that should be supported by the lib 🙏🏻

I just came across this limitation today. Would be phenomenal to have in this library!

Hey! This sounds reasonable, thanks for providing examples.

This could be accessible by tabBarBadgeStyle prop on the JS side.

PRs welcome 🙏
