WhiteboxTools v0.14

• This release largely focusses on bug-fixes rather than adding new features. However, the
  following tools for measuring surface roughness in a DEM were added to the project:
  CircularVarianceOfAspect
  EdgeDensity
  SurfaceAreaRatio
• Fixed a bug that resulted in rasters with projected coordinate systems being
  interpreted as geographic coordinates, thereby messing up the calculation of
  inter-cell distances for tools like slope, aspect, curvature, etc.
• Fixed a bug with several of the math tools; output files took their data type
  from the input file. In some cases, this does not work well because the input
  is integer and the output must be floating point data.
