[0.20.0] - The "I am GRU Release"

Achieved a High Score of 70 on the 20x20 Snake Game Board

Added

• Updated Event Log screenshot for the docs.
• Stagnation Hander
  • Introduced the concept of a stagnation event that is implemented in the TrainMgr.
  • A stagnation event is defined as occurring when no new high score has been achieved within a set number of episodes.
  • There are normal and critical stagnation alerts that are sent to the ATH Gearbox and Nice Policy object.
    • The Nice Policy activates the EpsilonNiceAlgo when a threshold is received and deactivates it when the event is cleared.
    • The ATH Gearbox gears down when a normal stagnation alert is received, unless it has recently shifted up.
    • The ATH Gearbox does a radical downshift to a sequence of 8 when a critical alert is received.
• A Gated Recurrent Network - GRU has been added.
• Epsilon Nice Policy and Algorithm
  • See the README for more information on this new feature.

Changed

• Updated PyPI and RTD documentation.

Fixed

• Scores image link in README
• HydraLog bug that caused duplicate log messages after a reset.
