Review test framework

[paskino]

Currently the few unit tests we have are running with the run_test.sh in the recipe directory, i.e. the tests are orchestrated by conda.

This means that the test files are always included in the package and it may not be what we want in the longer term.

Another option is to create new GHA to run CMake and CTest, and conda build just to create the package.
