statement_reconciler: Add initial Chase bank CSV statement matching

We currently don't have many examples to work with, so haven't done any
significant testing of the matching accuracy between statement and books.

Pin to Beancount v2

Beancount v3 has been recently released. It's a major rewrite and is currently
unstable and not compatible with this codebase. We need to remain on v2.

Add colorama dependency

Used by statement reconciler.

reconcile.helper: Avoid rt >= 3.0 library due to breaking changes

Error relates to rt.Rt not existing.

Add typing dependencies for requests, dateutil, setuptools and yaml.

Without these, mypy complains that "Library stubs are not installed".

query: Let the user interrupt interactive queries.

This makes it easier to iterate on a query because you don't have to restart
the program and reload the books if something goes sideways.

setup: Don't disallow untyped calls.

Unfortunately this is becoming more trouble than it's worth as we
call more and more untyped Beancount functions.
disallow_untyped_defs provides most of the value of what we really
want here, so go ahead and turn this off.

setup: Disallow untyped defs.

Mostly this meant giving annotations to low-value functions like
the error classes and __init_subclass__, but it's worth it for
the future strictness+documentation value.

setup: Enable stricter type checking.

This caught the "return instead of raise" bug in meta_project.
