chore: bump version

`footprint_has_field(footprint, 'dnp')` returns `False` for DNP
components in KiCAD v8.

In KiCAD v8 the DNP flag is available via either the IsDNP() getter or
the FP_DNP attribute.

The added `getattr()` call turns into `footprint.IsDNP()` in KiCAD v8 or
`bool()` (which evaluates into `False`) in KiCAD v7 and earlier.
