Parse SPICE Extraction feedback, Convert into KLayout Marker Database Format

[donn]

Steps

• Magic.*

  • All steps now use a new processor, openlane.steps.magic.MagicOutputProcessor, to capture and count errors

• Magic.SpiceExtraction

  • A feedback.xml is now created, with the contents being the SPICE Extraction feedback in the KLayout marker database format

Misc Enhancements/Bugfixes

• openlane.steps.DefaultOutputProcessor
  • %OL_METRICS_F now uses Decimals instead of Floats
• openlane.common
  • DRC: Work around a weird macOS-only bug where boxes in exported KLayout marker databases would not function properly: see https://github.com/KLayout/klayout/issues/1550
  • GenericDictEncoder: Fixed crash when attempting to dump a Decimal of infinite value
