Subject: [PATCH] Flatten arrays for wider awk compatibility

* The current implementation of the calendar heatmap by author
  contains multidimensional arrays. This works with newer versions
  of awk, but can cause issues with systems that use an older variant
  which cannot easily handle these calculations. macOS is especially
  impacted by this.

  By flattening the arrays from a multidimensional array to a single
  dimensional array, we can maintain greater compatibility across awk
  variants without requiring the user to install additional versions
  of awk.

Addresses issue #194
