Attempt to fix "conflict dependencies" error

[JackLonergan97]

When attempting to run "pip install .", there's a conflicting dependencies error from fgspectra 0.1 in the master and act_sz_x_cib branches. There were recent changes to the act_sz_x_cib version of fgspectra, so the changes made in the pull request are so that the two versions of fgspectra match.

Thanks @JackLonergan97 -- @xzackli could you take a look at this and see if it is OK? This is targeted to fix simonsobs/SOLikeT#20 where the soliket build fails on install.

@JackLonergan97 it's also possible that the soliket build for now just needs to point to a different branch of fgspectra as a dependency? Does the current lat_mflike do so?

[JackLonergan97]

@timothydmorton I think that would also work. It seemed like the error was popping up because there were two versions of fgspectra 0.1 referenced that had different code. So if both references pointed towards one of the two versions, that might fix the error.

See if it is possible to make a correction just to the setup.py file in soliket that fixes things without having to change anything within fgspectra.
