Commit fb823161a8e3dfc864a7bd83a9b968f4912c5b1d added a dependency of
JxlBitDepth, which wasn't present in 0.7.0. This updates the library
versions in ./configure required to match 0.8.0, the new required
version.

Version 0.8.0 was released about two weeks ago. Is this too recent?

Generally keeping backwards compatibility becomes more relevant when either:
1. the library is already stable and well-established
2. some addition can be easily #ifdef'd or so with version guards.
At this point the lack of this bump is failing compilation on my
Fedora 37 system as it currently still packages libjxl version 0.7.0,
so as it seems like libjxl is still in the process of adding basic
APIs, I'd maybe edge on the side of just bumping the requirement, even
if the bit depth feature itself isn't that critical and could in
theory be ifdef'd around (if libjxl even has useful defines for such
checks).

Since many distributions ship libjxl 0.7.0 still, we'd still prefer to
compile against that, but don't want to lose the features that require
libjxl 0.8.0 or greater. For this reason I've added preprocessor #ifdef
guards around the features that aren't necessarily in libjxl 0.7.0.

This is an alternative to the above patch. I replied it to the previous
patch so they can be compared but only one should be applied.
