The wrong PyPi package is picked up for some of my plugins

[asg017]

From https://datasette.io/plugins?sort=downloads-this-week , this reports sqlite-regex has the most downloads last week. But it's picking up the sqlite-regex package, not the datasette-sqlite-regex package (which has like 1/5th of the downloads)

It's a bit difficult to track down the source:

• In pypi-datasette-packages, only the datasette-sqlite-regex package is listed, but idk if this is picked up by datasette.io
• package-stats seems to have a github action that scrapes package download data, source from datasette.io with this query. That queries the datasette_repos table, which only lists "asg017/sqlite-regex" and not datasette-sqlite-regex

I think the solution would be to add a new optional pypi_package key to plugin_repos.yml, and to default to that over inferring the pypi package name from the repository name. That way, I can change the sqlite-regex entry to something like:

- repo: asg017/sqlite-regex
  pypi_package: datasette-sqlite-regex
  tags:
  - SQLite Extension
