Create new label classes with Arcpy

[GusMartinka]

Add the ability to create a new label class to arcpy labelClass. Changing label classes is nice but creating new ones is needed.

All they need to do is make sure arcpy.mapping.labelClasses can use the append() method for lists, and it's problem solved.  They had to have specifically removed this ability, as a list structure has it by default, so it's just a matter of removing the code that removed the ability.  I don't know why they ever took that out.  It's just not logical.

This will be available with Pro 3.3.

Layer.createLabelClass(name, expression, {sql_query}, {labelclass_language})
