Download as string
Add function to file_handler
that allows for downloading output as a string:
- The function should probably unzip the output in memory
- As multiple files can be archived into zip, the file should probably return Dict[str] (filename to output).
- Non-text data should be handled as a vector of bytes or ignored (we rarely have e.q. images as output).
- The function should be named something like
download_as_dict
(to be determined)
