@sjkelly do you mind merging this when you get a chance? The CI failure appears unrelated.

[sjkelly]

Hmm it looks like CI didn't run at all though...

[stemann]

#68 should fix CI (except for Invalidations) fixed CI

Not strictly related to this PR, but the repo is missing a tag/release for 0.6.7 it seems...

[IanButterworth]

Fixed, but TagBot isn't happy even though I updated it to latest config and refreshed the DOCUMENTER_KEY etc. so I had to make a manual release after the tag was made

[IanButterworth]

Going off tests passing, and TiffImages 0.10 being used in tests, this LGTM.

However, we claim to support a lot of older TiffImages versions. Maybe that's true but it highlights the general need to test lower compat bounds too
