Bulk insert mechanism in the insert row dialog

[simonw]

• Click "Insert multiple rows" from the insert dialog
• Paste in JSON or TSV or CSV - or drop on a file
• Preview table showing what will be inserted
• Rows get inserted via the JSON API
• Same UI is also available on create table, as "create table from rows", using existing API.

It's effectively https://github.com/datasette/datasette-import as a core feature.

Insert screen now looks like this:

Point of confusion: I tried importing the same external data (with a concrete primary key - it was the JSON from https://api.github.com/users/simonw/repos) twice - once to create the table, and then again with the edit feature.

This happened:

I guess I was actually trying to do an upsert here, which the UI doesn't yet support.

Need to think about if upsert should be a feature and how it should work.

Note that upsert requires an additional permission, update-row - not just insert-row.
