remove spice dependency from tests for updated lunarsky

[aelanman]

Description

The latest version of lunarsky drops the dependency on spiceypy. As a result, the try blocks that catch SPICEUnknownFrameErrors in unit tests can be removed. This also bumps the minimum version of lunarsky.

Motivation and Context

This cleans up code that will no longer be needed.

Build or continuous integration change checklist:

• If required or optional dependencies have changed (including version numbers), I have updated the readme to reflect this.
• If this is a new CI setup, I have added the associated badge to the readme and to references/make_index.py (if appropriate).

@burdorfmitchell I think we'll need you to update the lunar reference sim data before we can merge this PR. The new lunarsky version is available on pypi.

Thank you!!

hmm, @aelanman it looks like it's passing the test for array equality but it's somewhat slower than the older version.

We can merge it as is and make an issue for speeding up lunarsky if you like.
