CompilerGym v0.1.10

This release lays the foundation for several new exciting additions to CompilerGym:

• [LLVM] Added experimental support for optimizing for runtime and compile time (#307). This is still proof of concept and is not yet stable. For now, only the benchmark://cbench-v1 and generator://csmith-v0 datasets are supported.
• [CompilerGym Explorer] Started development of a web frontend for the LLVM environments. The work-in-progress Flask API and React website can be found in the www directory.
• [New Backend API] Added a mechanism for sending arbitrary data payloads to the compiler service backends (#313). This allows ad-hoc parameters that do not conform to the usual action space to be set for the duration of an episode. Add support for these parameters in the backend by implementing the optional handle_session_parameter() method, and then send parameters using the send_params() method.

Other highlights of this release include:

• [LLVM] The Csmith program generator is now shipped as part of the CompilerGym binary release, removing the need to compile it locally (#348).
• [LLVM] A new ProgramlJson observation space provides the JSON node-link data of a ProGraML graph without parsing to a nx.MultiDiGraph (#332).
• [LLVM] Added a leaderboard submission for a DQN agent (#292, thanks @phesse001!).
• [Backend API Update] The Reward.reset() method now receives an observation view that can be used to compute initial states (#341, thanks @bwasti!).
• [Datasets API] The size of infinite datasets has been changed from float("inf") to 0 (#347). This is a compatibility fix for __len__() which requires integers values.
• Prevent excessive growth of in-memory caches (#299).
• Multiple compatibility fixes for compiler_gym.wrappers.
• Numerous other bug fixes and improvements.
