Approvaltests

To avoid too many diff tools being launched, ApprovalTests will stop launching after the 5th time.
This is configurable in
python
GenericDiffReporter.throttling_threshold

MrJobApprovals mistakenly did not allow you to pass options, it does not.

This is an api change, hence the minor version bump

You can invoke a `verify()` call from the command line
This allows invoking python approvals from any other stack via subprocesses.

Usage:

python -m approvaltests --test-id hello --received "hello world!"

or

python -m approvaltests -t hello -r "hello world!"

or

echo "hello world!" | python -m approvaltests -t hello

What
You can now easily `verify` command line outputs.

You can also pass inputs into the command line under test, including Iterables.

Why
This allows you to easily test non-python programs from ApprovalTests.

How
[see example here](https://github.com/approvals/ApprovalTests.Python/blob/main/tests/utilities/test_command_line_callouts.py#L8)

Breaking Change

approval_utilities is becoming its own pypi package to allow usage in production code.

Fixes

You'll have some name spacing changes.
