Create Datatable

Import csv file and convert it into a threekit datatable. When using endpoint via API, columnInfo and name must be specified. The process can either be a sync or async. The sync process will create the datatable within in the lifespan of the API call. The async process creates a job whose status can be polled using the Get Job endpoint. Recommendation If a CSV has more than 100k cells, the datatable creation process should be async.
