(cad/klayout) Updated 0.28.7 to 0.28.8

0.28.8           (2023-05-23):
* Enhancement: %GITHUB%/issues/1314 Storing (arbitrary) data in metadata
  - Meta information can be attached to layout and cells
  - Meta information has a string key and arbitrary value (hash, list supported)
  - Optionally, meta information can be made persistent and
    is stored in the (KLayout specific) context section of GDS2 and OASIS
  - Meta information is shown in the user properties dialog, but is not editable
  - Meta information is similar, but not the same than user properties

* Enhancement: %GITHUB%/issues/1324 Feature request: hide empty groups

* Enhancement: %GITHUB%/issues/1345 feature request: create a def
  single/mulitpart path import option

* Enhancement: %GITHUB%/issues/1348 "Reload Files" popup prevents
  closing KLayout

* Enhancement: %GITHUB%/issues/1349 Add application events for

  area, not just label origin point

* Bugfix: Making 'R', 'L' and 'C' parameters for the respective Spice
  elements beside "value"

* Enhancement: Zoom In/Out menu functions now use the current mouse
  position for the zoom fixpoint (important when binding them to a
  key)

  properly made available (was for example RBA::Qt::Qt_Keys instead of
  RBA::Qt_Keys and pya.Qt.

Keys was no fully initialized type object)

* Bugfix: Netlist reader: anonymous circuits (without definition) will
  not fail because of unknown parameters

  mode

* Enhancement: Somewhat better grid snapping in partial edit mode
