ENH: sorptionWallFunction: new wall boundary condition

Summary

• Implementation of a sorption wall-function boundary condition for an arbitrary operand scalar in line with:​
  • Foat et al. (2022). Predicting vapour transport from semi-volatile organic compounds concealed within permeable packaging.​
  • Foat (2021). Modelling vapour transport in indoor environments for improved detection of explosives using dogs.
• New condition: sorptionWallFunction​
  • The sorptionWallFunction is a wall boundary condition to specify scalar/concentration gradient for turbulent and laminar flows.​
• Blending options:​
  • Stepwise (discontinuous) (Foat (2021) - (Eq. 5.3)​)
  • Exponential (smooth) (Foat et al. (2022) - (Eqs. 1-6)​)
  • Binomial (smooth)​
  • Tanh (smooth)​
  • Max (discontinuous)
