[Enhancement] Catch exceptions for individual photos so that it will not stop syncing of large photo library

[zhanglix]

Lychee may fail to process some photos in a large set of photos for various reasons such as corrupted photo, exceptional boundary condition.

Current, Gdhandler->crop() did not catch all exceptions so that it will stop the whole syncing procedure. And It is very difficult and tediously to location the photos which caused the exception.

It will be really nice if Lychee can skip and record photos which can not be processed and keep syncing other photos.
