Note there is a performance issue in this build - it wasn't introduced by these changes, but it 5-10 times slower than earlier versions (not sure how early to go to have it fast - was using 4.0.4

The palette colour data can come back as a promise, so that it is lazy loaded as required.
The conversion from palette colour is fast, but there does seem to be a rerender somewhere that is relatively slow in the newer version - this doesn't seem to be related to the changes here as I can revert them and it is still slow, but version 4.0.4 was faster.
Changed to have the image loader use async instead of promises to deal with a deep nesting of things.
