+Convert layer files from ArcGIS 10.x `*.lyr` to ArcGIS Pro `*.lyrx`

+An input folder is searched recursively, and a mirror folder structure will be
+created in the output folder with every `*.lyr` file replaced with the equivalent
+`*.lyrx` file.
+
+Requires arcpy from ArcGIS Pro and Python 3.6+
+This script will not work with arcpy from ArcGIS 10.x
