traumar 1.2.3

• probability_of_survival() was updated to enhance code readability and
  leverage mathematical notation in the calculation of predicted survival
  probabilities. The function now aligns with the coefficients published in
  Norouzi et al. (2013) and Merchant et al. (2023). Consistent with Boyd et al.
  (1987), the function does not treat patients under 15 years of age differently
  and accounts for penetrating injuries similarly to other age groups. This
  update ensures a standardized approach to calculating survival probabilities
  for both blunt and penetrating traumas.

• From this release forward, all development of traumar will be done in the
  IDE Positron!
