use updated stopping coefficients for hydrogen-like projectiles

- The stopping coefficients from ICRU Report 49 (published in 1993) are now
  fairly old, with many originating from the even older compilation by
  Anderson & Ziegler (published in 1977). For some target elements, little
  experimental data was available at the time of publication and the tabulated
  values are not necessarily reliable.
- This patch provides revised values for stopping coefficients in select
  elemental targets derived from Varelas-Biersack fits to stopping data
  compiled in the IAEA's database (https://www-nds.iaea.org/stopping/).
  For further details on their determination, see e.g.:
  https://doi.org/10.48550/arXiv.2212.11081
- When creating input files for trimspNL using the GUI, the default behaviour
  is changed to prefer using the revised coefficients. In instances where
  updated values are unavailable (e.g., due to lack of experimental data),
  fall back to using the coefficients from ICRU Report 49.
