* DDS: fixes for A8, L8, A8L8 formats While developing #3573 at one time I had them working properly, but then while fixing the address sanitizer failure for 3-channel formats I botched them again. Note to self: never again do a "yeah I'll add tests later", since if I had all of them running all the time this would not have happened. 🤦 * DDS: extend test coverage for more formats & channel size cases With more test images recently added (#3459), start using them for DDS tests. This covers now: - Alpha, Luminance and Alpha+Luminance formats, - RGB formats with rarer channel sizes (rgb10 a2, r3g3b2), - Several "broken" DDS file cases - Removed usage of sample-DXT1 since it is well covered by others.

Description
Somewhat in preparation of addressing #2338, this adds more images into DDS test suite. The actual images are at AcademySoftwareFoundation/OpenImageIO-images#4, this one is just using them in the test python script.
Tests
Yes, this PR is only about the newly added tests. Of course all the
ddstests are failing on CI without having the new images merged into the oiio-images repository (AcademySoftwareFoundation/OpenImageIO-images#4).Checklist:
have previously submitted a Contributor License Agreement
(individual, and if there is any way my
employers might think my programming belongs to them, then also
corporate).
(adding new test cases if necessary).
