Google Keep Image Cache per mdavis.xyz

In Google Keep you can add images (e.g. photos) to notes. However each time you revisit Google Keep to look at those notes, it will re-download the images. This is slow and wastes your laptop battery. This extension saves ('caches') the images locally, so that they appear almost instantly. It still can take many seconds for an empty note to be loaded, but once the text of the note appears, any attached images should appear instantly, instead of many seconds later.
