Support aiosqlite 0.22.0+

Fixed issue in the aiosqlite driver where SQLAlchemy's setting of
aiosqlite's worker thread to "daemon" stopped working because the aiosqlite
architecture moved the location of the worker thread in version 0.22.0.
This "daemon" flag is necessary so that a program is able to exit if the
SQLite connection itself was not explicitly closed, which is particularly
likely with SQLAlchemy as it maintains SQLite connections in a connection
pool.  While it's perfectly fine to call :meth:`.AsyncEngine.dispose`
before program exit, this is not historically or technically necessary for
any driver of any known backend, since a primary feature of relational
databases is durability.  The change also implements support for
"terminate" with aiosqlite when using version version 0.22.1 or greater,
which implements a sync ``.stop()`` method.
