pyTRS v2.2.0

• New Tract attributes (.aliquots, .aliquots_standard, .lots_aliquots, and .lots_aliquots_standard) to compile the parsed QQs (and lots) into larger aliquot blocks -- e.g., ['NENE', 'NWNE', 'SWNE'] to ['N2NE', 'SWNE'].
• New feature: Tract.quick_desc_lots_aliquots() -- same as .quick_desc() but using the recompiled aliquots attributes mentioned above.
• New feature: TractList.consolidate() to consolidate tracts within the same Twp/Rge/Sec, using the newly added Tract attributes mentioned above (.aliquots, etc.).
• New feature: TractList.quick_desc_lots_aliquots() and TractList.pretty_desc_lots_aliquots() -- same as .quick_desc() and .pretty_desc() but using the recompiled aliquots attributes mentioned above.
• Bug fix: deduce layout from preprocessed text, rather than raw text
• Other various bug fixes, minor improvements
• Misc. cleanup of readme, docs, and guides.
