feat: insert into sqlite tables

[tychoish]

Thanks to @vrongmeal for all the sqlite infrastructure and spotting my bug.

Should be good to go now.

This is close, but the test fails with a common error from SQLite on
the insert statement (e.g. attempt to write a readonly database). I'm pretty sure that this isn't due to the python sqlite
library which creates the db and sets things up, but something with
how we (probably?) create the sqlite client object.

Yeah, we do create the client in "read-only" mode:

glaredb/crates/datasources/src/sqlite/wrapper.rs

Lines 32 to 36 in 9c27dd0

	let inner = async_sqlite::ClientBuilder::new()
	.flags(OpenFlags::SQLITE_OPEN_READ_ONLY)
	.path(&path)
	.open()
	.await?;

In general, this looks good!
