In some tests, we have data files which are written with a particular hash algorithm. Instead of keeping two copies of the test files, we can keep one, and translate the value on the fly.
In order to do so, we'll need to read both the source algorithm and the current algorithm, so add an optional flag to the test_oid helper that lets us read look up a value for a specified hash algorithm. This should not cause any conflicts with existing tests, since key arguments to test_oid are allowed to contains only shell identifier characters.
