Incorrect data type used for column keyword

[JSKenyon]

• dask-ms version: 0.2.2
• Python version: 3.6.8
• Operating System: Ubuntu via WSL

Description

I updated all my dependencies to the latest versions today and I now get the following error message when attempting to set up a write to column keywords.

RuntimeError: TableRecordRep::defineDataField - incorrect data type used for field FLAGSET_legacy.

The value currently in that field is an int, as is the value I am attempting to write to it.

What I Did

I get the same behaviour outside of my project. I ran the following via iPython:

from daskms import xds_from_ms, xds_to_table

xds, kwrds = xds_from_ms("C147_unflagged.MS/", columns=("BITFLAG"), column_keywords=True)
xds_to_table(xds, "C147_unflagged.MS/", columns="BITFLAG", column_keywords={"BITFLAG": kwrds["BITFLAG"]}) 

Note that the above example does not edit the keywords - it just attempts to rewrite the existing keywords but it still falls over. This seems to happen whenever I attempt to write to a keyword which already exists and contains an integer value, or when I attempt to change the type of the value in an existing keyword.
