add ratir to load_image

[emirkmo]

I'm in the middle of a big refactor of Devel but needed to add RATIR as an instrument, so I am hoping I can merge this into Master after some tests.

@lgalbany should let me know though if the headers will be correct or not for the FILTER, or if I should also add in logic for dealing with their dual filter name headers.

It has also been added as site with id=23 on the flows website/database.

@rhandberg tagging you so that you can pull this when it's ready and if it looks ok.

The refactor also had me mess with the github actions so there are some with the regular release things.

Tests failed due to LFS bandwidth, which I upgraded now..
