Please add support library fragment

[tvdwal]

Dear Realexpayments,

We use android.support.v4.Fragment classes in our project and we cannot use them in combination with HPPFragment, which is of type android.app.Fragment. Looking at your code it would be possible to extend the HPPManager interface with something like manager.newCompatInstance() and return a HPPManager fragment with type android.support.v4.Fragment.

Addition: it might be better to completely change the library to use supportFragments because FragmentManager is deprecated since API 28

Are there any plans on resolving this issue?
