PySDM v2.54

What's Changed

• new examples & smoke tests (isotopes, no env.):
  • Gedzelman & Arnold 1994 fig 2 (fractionation upon evaporation in below-cloud subsaturated conditions)
  • Miyake et al. 1968 fig 19 (isotopic relaxation timescale)
• formulae:
  • isotope diffusivity ratios (Graham's law; Stewart 1975; Hellmann & Harvey)
  • isotope relaxation timescales (Miyake)
  • access to RogersYau terminal vel. from Formulae
  • refactor around Null classes (removal of all but one null.py files)

PySDM v2.48

What's Changed

• remove references to constants_defaults from the README snippets (+ add Formulae::get_constant()) closes #1243 by @slayoo in #1269
• switch from empty to full(nan) in FakeThrust Storage and from full(-1) to full(NaN) in Numba to help spotting on CI cases of uninitialised memory access by @slayoo in #1201
