smoke test comparing dry/wet equilibrium calculation against PyPartMC (thanks @zdaq12) avoiding divide-by-zero warnings in EffectiveRadius product fix physical unit in size-spectrum products (thanks @sajjadazimi) better array-valued argument handling in Formulae methods using numba.vectorize (thanks @claresinger) new method: Builder::replace_dynamic() (@edejong-caltech) handling NVRTC_PATH env var to point ThrustRTC to non-standard location of nVidia libs (@abulenok) new backend methods: min_pair, divide_if_not_zero (@edejong-caltech) GPU support for freezing 3D displacement incl. GPU support (@abulenok) Straub fragmentation function (@edejong-caltech) breakup algorithm improvements incl. reworked limiter logic, fragment_size instead of min_volume, fragmentation function updates (@edejong-caltech) backends: fixed __init__ calls in multiple-inheritance contexts FakeThrust fixes to better match ThrustRTC API (@abulenok) make formulae available at attribute mapper scope so request_attribute can be called without constraints storage, attribute, mesh common code: improved test coverage, cleanups, docstrings (@abulenok!) multi-stage Github Actions workflow (pylint, no-numba unit tests, etc first, only then run all the tests updates to make the code clean with newer versions of pylint new tests for displacement, freezing, breakup, mesh, builder, formulae and storage logic
