[cudaaligner] Tests should load data from file

[ahehn-nv]

cudaaligner's tests use hard coded test data. This data should be loaded from data file(s) instead (like cudamapper).

cudaaligner's hard coded data: https://github.com/clara-parabricks/GenomeWorks/blob/dev-v0.5.0/cudaaligner/tests/cudaaligner_test_cases.cpp

cudamapper's data and tests: https://github.com/clara-parabricks/GenomeWorks/tree/dev-v0.5.0/cudamapper/data and https://github.com/clara-parabricks/GenomeWorks/tree/dev-v0.5.0/cudamapper/tests
