fix(android): Fixed exif handling when loading picture from gallery

[mariusvn]

Platforms affected

• Android

Motivation and Context

The exif data was removed if we loaded from the gallery in DATA_URL format.

This should fix #867.

Description

Instead for returning the bitmap compressed and encoded in base64, we save it into a file, and apply the input exif data and then we put it back in the memory to encode it in base64 and return it.

Testing

I tested my changes in an ionic app that use this feature via @awesome-cordova-plugins/camera@5.46.0
