support render_postcompile

[aminalaee]

Fixes #377

The behavior of IN and NOT IN Bind parameters have changed to POSTCOMPILE which will expand parameters on the fly.

SQLAlchemy changelog here.

stmt = select(A.id, A.data).where(A.id.in_([1, 2, 3]))

>>> print(stmt)
SELECT a.id, a.data
FROM a
WHERE a.id IN ([POSTCOMPILE_id_1])

We should either use literal_binds with compile:

>>> print(stmt.compile(compile_kwargs={"literal_binds": True}))
SELECT a.id, a.data
FROM a
WHERE a.id IN (1, 2, 3)

Or use new render_postcompile helper:

>>> print(stmt.compile(compile_kwargs={"render_postcompile": True}))
SELECT a.id, a.data
FROM a
WHERE a.id IN (:id_1_1, :id_1_2, :id_1_3)

Thanks for that!
I guess a 0.5.1 should be done
