The OpenCV image_processing component accepts a `min_size` argument in
each classifier that is then passed into the OpenCV library. The
`min_size` argument is expected to be a tuple of 2 ints, and is entered
into the platofrm schema as such. However, yaml will always produce a
list instead of a tuple, which means in practice it's impossible to use
the `min_size` argument. This changes the schema to accepts any sequence
of 2 ints that is then coerced into a tuple suitable for passing to the
OpenCV library.
* Consolidate
* Fix tests
* Update imports
* Fix import
* Use importlib because integration and package share name
* Fix more tests
* Update .coveragerc and CODEOWNERS
