v0.13.0

• Corrects encoding of test logs, binary data should no longer show in the output (closes #4)
• Overhauls the webhook flow
  • Users can now configure their own comma separated list of ALLOWED_BRANCHES
  • Previously a webhook secret was required; now, Harvey will run Pipelines without a webhook secret (bypassing decoding and validation of the previously non-existent secret) if there is no WEBHOOK_SECRET variable set
  • Additional refactor surrounding how we validate webhook secrets
• Fixed the container healthcheck when using the compose workflow - this was accomplished by making the compose and non-compose container names uniform
• Bumps dependencies (Flask 1 to Flask 2) and now requires Python 3.7. Also removes the mock library in favor of the builtin unittest.mock library
• Various code refactors and bug fixes
