0.5.0 Release (#4)

- concurrency: always run with only 1 work in default run script and in Dockerfile
- timestamp check: ensure the 'created' timestamp is no newer than signed timestamp and no older than duration, not other way way around
- typing: set model to use datetime for signed request and signed hash, use dateutil for more accepting parsing
- linting: add pylint testing, add missing docstrings, ignore extraneous warnings

improved logging:

- on cert failure, output full stack trace
- don't call function on invalid attribute to avoid raising another exception
