UVC Camera Android

UVC Camera Android is a library that allows for the use of USB cameras on Android devices. The library was brought over from the hthetiot/UVCCamera repo which is a fork of saki4510t/UVCCamera. The fork was used as it has been updated for later android versions.

7. Added generated libs folder dependency to library `build.gradle``

Modifications

Normally to grab the frame data you would need to render it on a surface and then you would be able to get the frames. The UVCPreview.cpp was modified, mostly the do_capture_callback, to bypass the requirement of rendering it on a surface. The gist of changes can be found from this closed issue, but there are some differences between the actual implementation and the issue.
