casacore missing as a dependency

[Mulan-94]

Hi there,

Trying to run mvftoms --help and I get:

Traceback (most recent call last):
  File "/home/v_envs/katdal/bin/mvftoms.py", line 39, in <module>
    from katdal import averager, ms_async, ms_extra
  File "/home/v_envs/katdal/lib/python3.8/site-packages/katdal/ms_async.py", line 36, in <module>
    from . import ms_extra
  File "/home/v_envs/katdal/lib/python3.8/site-packages/katdal/ms_extra.py", line 27, in <module>
    import casacore
ModuleNotFoundError: No module named 'casacore'

installing python-casacore seems to help. Perhaps it's a missing required dependency?

Tested on: python 3.8

Casacore is an optional dependency for katdal. Install with the square bracket notation [ms,s3]

Indeed, as @bennahugo said: pip install katdal[ms].

The s3 option still exists but does nothing. It is safe to leave that out.
