`sqlite-diffable load` command for restoring a dump

[simonw]

The reverse operation to sqlite-diffable dump - this will create a brand new SQLite database using the data in the specified directory.

sqlite-diffable load mydb.db path-to-directory

I find myself wanting this today because I want to turn my https://github.com/simonw/simonwillisonblog-backup repo into a SQLite database.
