0.3.5

Minor release mainly aiming at polishing existing features and addressing some major performance regression that was introduced end of august. GsTaichi dynamic array type and fast cache are now enabled by default on Linux and Windows (opt-in on MacOS via env variable 'GS_ENABLE_NDARRAY'), which should help avoiding recompilation in most cases.
