si/test: Add tests for range encoding/decoding

This commit adds test range encoding tests. They check the property
decoding(encoding(L)) = L and optionally dump the results and
encoded sequences to stdout.

There a 2 test modes:

 - A list of fixed tests
 - A random number based test loop per ARFCN list size (only dumps
   the first failing test)
