Minor bug fixes

This release introduces two minor bug fixes:

• REFLECT was added to effects, as it is used as such in gen 1 by pokemon showdown
• A typo in Pokemon._start_effect was preventing some effects from being tracked correctly

Add counters and misc improvements

• Add dynamax parsing / generation in teambuilder submodule
• Switch pokemon-showdown recommended version from custom fork to smogon master with custom CLI flags
• Add Effect counters
• Add Weather counters
• Add Field counters
• Add first turn per pokemon tracking
• Add status counters
• Parse cant messages
• Add sets of special Effects and Moves and matching properties in their respective classes

Misc bug fixes:

• Fix a rare issue in vgc hp parsing where a g character can appear in hp update information
• Add CELEBRATE and G_MAX_CHI_STRIKE effect
• Metronome battles are now double battles
• Add dedicated powerherb and sky drop dedicated cases for battle state tracking

Count battle side conditions

This release transforms the way side conditions are tracked in Battle objects: instead of being represented as a set of SideCondition objects, aide conditions are now dict mapping SideCondition to ints.

Add an option to start the timer at the start of each battle

This release adds an init option to each Player class: start_timer_on_battle_start. Setting it to True will make the player request the timer at the start of each battle.

Add preliminary gen 4, 5 and 6 support

This release introduces preliminary gen 4, 5 and 6 support. It introduces and / or adapts missing mechanisms and showdown quirks that are specific to these past gens. Additionally, it:

• Adds Gen4EnvSinglePlayer, Gen5EnvSinglePlayer and Gen6EnvSinglePlayer classes
• Adds defaults battle formats for EnvPlayer children classes. In particular, GenXEnvSinglePlayer now automatically defaults to genXrandombattles. EnvPlayer defaults to gen8randombattles.
• Fixes misc issues in Effect names.

Misc bug fix

This releases adapts to updates in showdown's protocol and introduces a more tolerant system for dealing with unrecognized showdown messages (ie. log a warning instead of raising an exception).

Misc effects

This release adds Enum values in poke_env.environment.effect.Effect.

Performance optimization

This release is focused on performance optimization, and includes a reduction of ~30% to 40% in message handling time. This is mainly achieved through a more performant json de serialization library, better caching and many minor optimizations.

Additionally, a couple of missing Enums were also added.

This release also includes BattleOrder objects, which are wrappers of messages sent to showdown during a battle.

Fix bug where max moves where stored in `Pokemon.moves`

0.4.1
