This issue is about how best to pass additional options to tools used for publishing datasettes. A concrete example is wanting to pass the --tar flag to the heroku CLI tool. I think there are at least two options for doing this: documentation for each publishing tool to explain how to set flags via env variables (if possible) or building a mechanism that lets users pass additional flags through datasette.

When using datasette publish heroku binder-launches.db --extra-options="--config facet_time_limit_ms:35000 --config sql_time_limit_ms:35000" --name=binderlytics --install=datasette-vega to publish https://binderlytics.herokuapp.com/ the following error happens:

``` › Warning: heroku update available from 7.42.1 to 7.43.0. › Warning: heroku update available from 7.42.1 to 7.43.0. › Warning: heroku update available from 7.42.1 to 7.43.0.

After installing GNU tar with brew install gnu-tar and modifying datasette/publish/heroku.py to include the --tar=/path/to/gnu-tar publishing works.

I think the problem occurs once your heroku slug reaches a certain size. At least when I add only a few 100 entries to the datasette then the error does not occcur.

datasette version 0.49.1 OSX 10.14.6 (18G103)
