Addition of ULTRASAT Configuration Files

[weizmannk]

This pull request introduces a series of updates to the gwemopt project. The updates include the inclusion of ULTRASAT configuration files, the addition of "params" to the lightcurve module to allow direct capture of filters specified by the user via the command line instead of using a fixed default filters, the introduction of arguments for location and observability, and the implementation of observability thresholds.

Hi! @mcoughlin
Here is the pull request. Now, everything should be okay as it's working fine. However, the warning is still present (you know we already discuss about it and you were waitting for @Theodlz . Another issue I've encountered is that I cannot use the --doMovie argument because ffmpeg, as referenced here https://github.com/skyportal/gwemopt/blob/main/gwemopt/plotting/movie.py#L21, is not functioning, and I'm unsure how to fix it. I was running it on LHO, so I didn't have sudo access to install this package. Could you please explain what exactly ffmpeg is and how I can install it on a server without sudo privileges?

@weizmannk Can you please run your pre-commit and fix the linting on these files?
