sci-chemistry/chemex: fix mysterious overdependency on tomli

In upstream version 2024.02.09 some "refactoring" was done:
97d6896836

It dropped support for python 3.10 and required the stdlib tomllib
rather than trying tomli. And sure enough, when 2024.02.16 was added to
::gentoo, it excluded 3.10 support for this exact reason. But it didn't
state why, and it didn't remove the out of date tomli dependency.

Remove it now.
