[dur] Add support for alignments and negative offsets + Ly logo (#893)

## What are the changes about?
Add support for letting a user use a negative offset (#880), alignment, and logo. Below is example of the logo file, I hope it is what was request :). It has no padding so a user can move the alignment and offset to get it how they want on screen.

This technically is good to go, except I didn't upload the logo file as I'm not sure where to add the animation file to get it to here: $CONFIG_DIRECTORY/ly/example.dur

- [x] I have tested & confirmed the changes work locally
