Lrowacphomap needs to be re-added and refactored with tests

[cordellmichaud]

Description

The lrowacphomap app needs to be re-added to enable applying photometric correction to WAC cubes with a parameter cube defining Hapke model parameters for the correction, a PVL file defining the algorithm, and an optional backplane cube.

Lrowacphomap also needs an update to be brought in line with the newer testing process for ISIS by refactoring lrowacphomap to be callable and adding functional tests to validate output.
