Grant/Revoke Uri permissions

[sam-maverick]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-file-provider@1.1.0 for the project I'm working on.

I am using this library for creating Uri links that other apps can use to access shared files in Android. However, in my case I need to grant and revoke permissions for that Uri, so that the other app can access it. As I have not found other libraries implementing this, I am attaching the suggested modifications to implement the grantUriPermission() and revokeUriPermission() methods.

More info here:

https://developer.android.com/reference/android/content/Context#grantUriPermission(java.lang.String,%20android.net.Uri,%20int)

Here is the diff that solved my problem:
