  * `munsell2rgb()` now safely selects the closest Munsell value and chroma to those available in the package LUT 
  * new function `soilTextureColorPal()` for suggesting a color palette suitable for soil texture class

  * `estimatePSCS()` gains argument `"lieutex"` for in lieu textures which are used in the new routine for identification of the particle size control section of organic soils
  * new function `collapseHz()` combines and aggregates data for adjacent horizons matching a pattern or sharing a common ID
  * new function `mutate_profile_raw()` for building sets of dynamic mutate expressions. Also `mutate_profile()` gains col_names argument for dynamic naming of columns.
+ * `addVolumeFraction()` now more robust to very thin horizons x low volume fractions; also skips horizons without sufficient or relevant values
