From @saqimtiaz in Discord:
Given a base64 encoded string representation of a PNG image, how would you recommended passing it to wnfs.add() to save the image to the file system?
Convert to a Blob? As is? I thought I had this working a couple of weeks ago but apparently not quite. Any input appreciated. (This is on webnative 0.24.1 working with the tiddlywiki-on-fission repository)
