This release adds the ability to execute queries joining data from more than one database file - similar to the cross database querying feature introduced in Datasette 0.55.

• The db.attach(alias, filepath) Python method can be used to attach extra databases to the same connection, see db.attach() in the Python API documentation. (#113)
• The --attach option attaches extra aliased databases to run SQL queries against directly on the command-line, see attaching additional databases in the CLI documentation. (#236)
