Unable to exclude tables

[ceedon]

Heya,

I'm interested in using tuql with litestream, but they don't play nice atm.
Extending the query in schema.js that excludes sqlite_% tables to exclude _litestream_% tables fixes it up.

A) Are ya interested in a PR that adds the ability to exclude other tables?
B) If so, any preference in how that's implemented?

Thanks for the nifty tool!
