As per get_container() but to connect to Azure Table Storage.

We're using Azure Table Storage in NHP work to host a lookup table that identifies scenarios with a run stage (final_report_ndg2, etc) and the sites to filter results by.

Data generation and upload happened in an nhp_analysis folder. The nhp_tagged_runs repo is reading from Azure Table Storage to prepare it into an interactive human-readable RMarkdown file.

It would be good for nhp_tagged_runs (and some other repos like nhp_final_reports) to use a generic {azkit} function to read from Azure Table Storage, rather than use copy-pasted functions.
