CasJobs client returns string columns typed as 'object' instead of 'str' when format='pandas'

[dobos]

Try this in a notebook:

df = CasJobs.executeQuery(sql="SELECT TOP 1 run2d FROM SpecObj", context='DR16', format="pandas")
print(df['run2d'].dtype)

The column type should be 'str' and not 'object'
