py-peewee: updated to 3.13.3

3.13.3
Allow arbitrary keyword arguments to be passed to DataSet constructor, which are then passed to the instrospector.
Allow scalar subqueries to be compared using numeric operands.
Fix bulk_create() when model being inserted uses FK identifiers.
Fix bulk_update() so that PK values are properly coerced to the right data-type (e.g. UUIDs to strings for Sqlite).
Allow array indices to be used as dict keys, e.g. for the purposes of updating a single array index value.
