Research direction

Start with the SQLite JSON1 documentation and the linked loopback-connector-postgresql commit. Trace how this connector handles nested JSON paths for the requested Customer where and order example, then verify that JSON extraction works while values remain TEXT.

Description of feature (or steps to reproduce if bug)

SQLite3 3.38 of Feb 2022 has support for json extract -> not unlike Postgres and MySQL. This connector should be updated to use that if possible.

No data type change is needed -- it's still TEXT.

Expected result

I hope the final interface is the same as the Postgres connector. The PG example is:

Customer.find({
  where: {
    'address.state': 'California'
  },
  order: 'address.city'
})
Additional information (Node.js version, LoopBack version, etc)

Eh, doesn't really matter here. No code for this stuff present is no code for this stuff present.

It's also not like people use loopback with sqlite3 for super serious business things, so don't put the priority too high. It's just nice to make it capable of this JSON stuff so people can experiment on a minimal setup.
