Simulations require full polarization #481

I am trying to simulate data in XX and YY only, but pyuvsim currently only supports Npols=4.

This is actually related to using multithreading, and specifically to using the mpi.big_bcast command. Something is getting lost when the uv object is broadcast across threads in that way. I need to look into this further.
