LocalCacheManager does not use consistent naming when hashing between sessions #41

When I run the ModelSearcher in different sessions, I noticed, for the models that have long names corresponding to the cached file (and therefore need to be hashed), the models will rerun despite having cached files.

I found out that the built in hash function returns different values across sessions. https://stackoverflow.com/questions/27522626/hash-function-in-python-3-3-returns-different-results-between-sessions

will use:

import hashlib
hashlib.sha224('example_file_name'.encode('utf-8')).hexdigest()
