Implement bash script for testing

Added formatting functions to translate_ciphersuite.py to take a string
of multiple ciphersuite names, in the current compat.sh and output the
translated ciphersuite names in the same format

Created test_translate.sh which uses samples from compat.sh to compare
against the translated versions to ensure the translations are produced
in the correct format
