Use logger in favor over print statment.
This is explicitly supported and encuraged by pytest, which also allows
for capturing logs separate from stdout calls, which is handy for when
e.g. lix code calls out to stdout to keep those differentiated from test
output

separating the nix fixture from the __init__.py file to increase
readability and overview over the existing fixtures

There is absolutely no good reason these should show up in NARs besides
misconfigured systems and as long as the case hack exists, unpacking
such a NAR will cause its repacking to be wrong on systems with case
hack enabled.
This should not have any security impact on Lix to fix, but it was one
of the vectors for CVE-2024-45593:

This also rewrites a lot of the command handling in the fixtures
library, since we want to more precisely control which way that the nix
store is set up in the tests, rather than the previous method of
renaming /nix/store to some temp dir (which allows builds but does not
allow any /nix/store paths or stability across runs, which is a
significant issue for snapshot testing).
It uses a builder to reduce the amount of state carelessly thrown
around.
The evil NARs are inspired by CVE-2024-45593
(https://github.com/NixOS/nix/security/advisories/GHSA-h4vv-h3jq-v493).
No bugs were found in this endeavor.
