Closes #19

See merge request !68

This adds a CI special job that runs only on merge requests that update
the test git ref, indicating that a noise has been changed.  The MR will
show present a report of the changed noises, and will block on MR approval.
Once approval has been given, the check_approval job can be re-run, which
should now pass, allow the MR to proceed.

If the noises change but the reference has not been updated, then the CI
pipeline will fail as usual.

This updates the test infrastructure to store a git hash of the reference
code, instead of generated .h5 files.  The test infrastructure creates a
cache of reference .h5 files from the specified git hash if it doesn't
already exist, and then compares against that cache.

Comparisons against arbitrary git hashes can be specified manually.
The cache curves are generated from a shell script so that it uses the
checkout of the python code at the reference commit.  Multiple caches based
on git references are stored, and old caches are automatically pruned to
keep just the latest five.

This gets rid of the need for git-lfs and the cached .h5 files, requiring
instead the code be checked out from git to run the tests.

Some cleanup and updates on the CI, including:
* creating a common docker image for all jobs
* expose test failure report to merge requests

Use overlaid dashes for the head traces.

Also do comparison in preferred IFO order.

These changes improve the modeling of suspensions that have a
temperature gradient along the fibers.  Each stage is split into an
upper and a lower joint, which can have different material properties
assigned in the ifo structure.  The temperature of a joint is that of
the mass to which it is attached.  (However, temperature gradients are
not yet supported within the top or bottom stages.)  The average of
the upper and lower joint dissipation is used to compute the noise.

closes #19

Just use a single argument of the form 'flo:npoints:fhi', instead of
three separate arguments.

no functional change, just limits individual function imports to non-array
operations.

Added Mac file .DS_Store to .gitignore

(cherry picked from commit b253c97e)

Removed normalization of sinc_sqr in dhdl because it is one at DC. Previously the normalization was set by the first frequency point, which is wrong if only high frequencies are considered

Add SQL noise type

It's sometimes helpful to have an SQL noise curve on noise budgets.
