Allow users to specify columns names for columnar format vector datasets #987
Description
Is your feature request related to a problem? Please describe
When using OSB with a custom HDF5 vector dataset users will find the column names of their .hdf5 must exactly match the "train"/"test"/ect fields hard coded by OSB.
Describe the solution you'd like
It would be convenient if these column names were configurable, maybe as part of the workload or some other flag.
Describe alternatives you've considered
The alternative is to recreate the .hdf5 file with a python script. A helper could be provided as an alternative but this can be a bit of a hassle as these .hdf5 datasets might be quite large and take some time to convert.
