selectedItemTextFontFamily and itemTextFontFamily props should be optional

[balsick]

Hi! 👋

Today I used patch-package to patch react-native-wheel-picker-android@2.0.6 for the project I'm working on.

While most props are set as optional, selectedItemTextFontFamily and itemTextFontFamily don't, but considering the README and the normal usage of the component, they should be set optional as well.

Here is the diff that solved my problem:
