analog-nihil-dark,analog-nihil-light: add two watch faces

[turretkeeper]

Add a faithful recreation of the stylish clock widget design by Nothing, as seen here:

Comes in light and dark versions.

Sorry for the late reply! :)

Thank you for the contribution! Just a couple of comments:

• Nothing seems to be a trademark, could you remove references to their brand ? we prefer avoiding referring to other brands ;)
• Since you're not using any of the QtGraphicalEffects, those import QtGraphicalEffects 1.15 lines aren't necessary and should make the watchface loading a tad bit faster ;)

Thank you for this great addition to the community watchfaces!

The brand name use should be avoided for legal reasons. A quick idea for a rename in case you are not an english native speaker, is to translate it to your language. Or find an idiom or analogy (like zilch, nil, nuttin.. etc) in case we stay in english :D

My requested changes are removing the QtGraphicalEffects import and adding yourself to the contributors list. You can do that in pseudonym (i.e. use your username) as long as you use that name across your contributions to AsteroidOS. Just in case you do not want to reveal your real name.

The svg optimization is not a blocker for this PR.

Thanks again for your contribution and sorry for the long wait for a review.

Addressed. analog-nothing is now analog-nihil, and the import is gone.
