Allow touches to pass through transparent KeyboardAccessoryView (pointerEvents)

[lafiosca]

Hello! Thanks for the great library!

In our app I'm using a KeyboardAccessoryView with a transparent background. It has a text input along the bottom and some floating action buttons in a column on the right. There is a large, unused, invisible portion of the view (to the left of the FABs) which I would like to be able to click through to the underlying content. My suggestion is to add pointerEvents="box-none" to the three Views here:

react-native-keyboard-accessory/src/KeyboardAccessoryView.js

Lines 161 to 162 in 4f98a2b

	<View style={{ height: (isKeyboardVisible || alwaysVisible ? visibleHeight : 0) }}>
	<View style={[

and here:

react-native-keyboard-accessory/src/KeyboardAccessoryView.js

Line 172 in 4f98a2b

<View onLayout={this.handleChildrenLayout}>

or to expose this functionality as an optional prop. For now I am using patch-package to accomplish this in our app.
