update to newer kicad API

[fenugrec]

I'd like to try this on current Kicad (7), but running into issues :

AttributeError: 'BOARD' object has no attribute 'GetModules'

Ok, replace GetModules( with Footprints( seems to help.

AttributeError: module 'pcbnew' has no attribute 'BOARD_GetStandardLayerName'

Ok, a bit tricker, not sure if strictly correct : replace that bit with pcbnew.BOARD.GetLayerName(pcb,layer)

And then, this one has me stumped :

Traceback (most recent call last):
  File "..../kicad_picknplace_assistant.py", line 220, in <module>
    create_board_figure(pcb, bom_row, layer=layer)
  File "..../kicad_picknplace_assistant.py", line 16, in create_board_figure
    ax = plt.subplot("111", aspect="equal")
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.11/site-packages/matplotlib/pyplot.py", line 1425, in subplot
    key = SubplotSpec._from_subplot_args(fig, args)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.11/site-packages/matplotlib/gridspec.py", line 574, in _from_subplot_args
    raise ValueError(
ValueError: Single argument to subplot must be a three-digit integer, not '111'

isn't 111 already a three-digit integer ?
[EDIT] well that error was surely written by the Sphinx, the code has "111" instead of 111 !

Next :

AttributeError: 'FOOTPRINT' object has no attribute 'GetFootprintRect
