CompilerGym v0.2.3

This release brings in deprecating changes to the core `env.step()` routine, and
lays the groundwork for enabling new types of compiler optimizations to be
exposed through CompilerGym. Many thanks to code contributors: @mostafaelhoushi,
@sogartar, @KyleHerndon, @uduse, @parthchadha, and @xtremey!

Highlights of this release include:

- Added a new TextSizeInBytes observation space for LLVM.

- Added a new PPO leaderboard entry

- Fixed a bug in which temporary directories created by the LLVM environment
  were not cleaned up.

- The function createAndRunCompilerGymService() now returns an int, which is the
  exit return code.

- Improvements to the examples documentation and FAQ.

Deprecations and breaking changes:

- CompilerEnv.step no longer accepts a list of actions. A new method,
  CompilerEnv.multistep provides this functionality. This is to provide
  compatibility with environments whose action spaces are lists. To update your
  code, replace any calls to env.step() which take a list of actions to use
  env.multistep().

- The arguments observations and rewards to step() have been renamed
  observation_spaces and reward_spaces, respectively.

- Reward.id has been renamed Reward.name.

- The backend protocol buffer schema has been updated to natively support more
  types of observation and action, and to support nested spaces.
