Batching updates with the Google Sheets API

[Skaft]

To better handle channels with high traffic and many applicants, it would be useful to bundle applications and update the sheet with multiple users in one API call.

The sheets API does have a batchUpdate endpoint, and gspread has an interface to it. What I have not found is a flexible way to create the payload. Perhaps a module is needed that generates dicts matching the Sheets API's Request object structure, for each common sheet operation done here. It seems trivial then to bundle any collection of such Requests and batch_update them in one go.

This could also be used to dodge some other redundant API calls, for example in refresh_headers.
