Connections created with sqlite3.connect(autocommit=True) make
commit() a documented no-op, and autocommit=False connections are
permanently inside a transaction - in both modes every write made
by this library appeared to work in-process but was silently
discarded when the connection closed. Database() now raises
TransactionError for these connections instead of losing data.
Tests are skipped on Python versions before 3.12, where the
autocommit parameter does not exist.

with Database(...) closes the connection on exit without
committing, so uncommitted changes are rolled back. This was the
existing behavior but was undocumented and untested - it is now
stated in the docs and pinned by a test.

* Pass a tracer= function to Database constructor
* New db.tracer() contextmanager
* Neater SQL indentation, because tracer means it could be visible now
* New db.execute() and db.executescript() methods
Closes#150
