v1.2.0

• Added ability to generate an editable schematic from a Circuit object. (Currently only works for KiCad V5.)
• Added Group object for creating hierarchy without using function calls.
• generate_pcb now takes an optional list of footprint library directories.
• If not explicitly declared, Part objects will load the default footprint from their symbol definition.
• Added empty_footprint_handler() for parts without footprints that logs errors by default but can be overriden by the user.
• Symbol libraries can now be searched on remote repositories by placing the URL in the lib_search_paths dictionary.
  KiCad V6 symbols are found at https://gitlab.com/kicad/libraries/kicad-symbols/-/raw/master
  and V5 symbols are at https://raw.githubusercontent.com/KiCad/kicad-symbols/master/.
• Part pins can now be sorted and retrieved in order using the ordered_pins property.
