Fix SQLite incompatability
Window versions were introduced in SQLite v 3.25.0. This means that the query within rangesForSystem() in queries.dart won't work on iOS versions < "13.1.3" (https://stackoverflow.com/questions/14288128/what-version-of-sqlite-does-ios-provide) and android versions < "11.0" (https://stackoverflow.com/questions/2421189/version-of-sqlite-used-in-android)
This PR updates this function to use an alternate query on SQLite versions that don't support window functions.
If you go to https://sqliteonline.com , you can run this to get the idea behind how the new query works:
SELECT *, ROW_NUMBER() OVER(ORDER BY Name, id) as rn FROM demo;
SELECT *,
(SELECT COUNT(*)
FROM demo as d2
WHERE demo.Name > d2.Name OR (demo.Name = d2.Name AND demo.id >= d2.id)
) as rn
FROM demo ORDER BY rn;
I tested this on an Android 9 device and it worked
