Big upgrade to the Section Township and Range tool: more detail, more flexibility, new labels

After the infrastructure upgrade I mentioned in the last post, the increased speed of the maps enabled me to add much more detail to the very very large map layers (over 12 Gigabytes!) that comprise the Public Land Survey System (PLSS), also known as Section, Township and Range.
