Add headerContainerStyle to components

[abbottdev]

Feature request

In order to really make a custom header I need to be able to control flex props of the parent container to the Headers that are used throughout the library.

An example:

sticky-parallax-header/src/primitiveComponents/withStickyHeader.tsx

Line 62 in 72b2155

{renderHeader ? <View onLayout={onHeaderLayoutInternal}>{renderHeader()}</View> : null}
