offload notification fonts to sender

[ChromiumOS-Guy]

There was an issue about it that was closed as not planned, but please reconsider adding the feature to load notifications as bitmap, the divergence from that suggestion is that I propose letting the sender send a bitmap and for InfiniTime to just display it, that way there are less constraints because there is no need to convert charterers on device so we don't need to store all the international fonts to support all languages just bitmap support.

dare I say it may free up some space because you won't need to support notification rendering beyond the bitmap, so you can remove all non-basic ASCII like emojis that you won't use in the UI itself. Although it is debatable if you want to outright remove the current system perhaps a dual approach will be better, I don't know enough to tell.
