Makes model substitution (VRML->STEP in STEP Export) optional. This can
prevent nasty surprises where the user doesn't see/can't affect the
outcome
Also, when substituting models, do not maintain scale factor. So a VRML
model with non-unity scaling will not be export as a STEP file (of the
same name) with non-unity scaling. This is the first step to address
https://gitlab.com/kicad/code/kicad/-/issues/1781
It would be ideal if it would use the s-expr
kicad_pcb.general.title_block.title by default, and then fall back to
something based on the output step file, but even just the output step
file is a far better default than the "open cascade step translator
version..." text it uses at the moment.
Similar improvements using the title_block would be future work.

FreeCAD uses gzip-based stpZ files but many programs will compress using
the archive format of PKZIP (e.g. WinZIP). This handles the archive
format, taking the first file from the archive, which by the standard
should be the STEP file

- Better code and messages.
- Speedup calculations when removing cutouts and holes from main board.
- Do not stop step generation when trying to load a 3D modele having issues.
The addition of very small segments in OCE triggers sliver
removal/cleanup in the BREP generation that can get stuck in a very long
loop during STEP export of boards. These were introduced to ensure
closure of boards with small gaps that were too big for OCE to consider
joined.
Removing the small segments allows STEP export to proceed in a
reasonable time. This also decreases the default minimum gap size that
kicad2step uses to determine curve matching. This prevents mis-matching
small curves

STEP exporter keeps outline contiguous by storing the last point
coordinates and using them as the starting point for the next segment. It
might create a problem for arcs, as one of the arc end points may become
translated (changed to the last outline point), while the remaining
points (center and the other endpoint) are kept original. For large
deltas it renders an arc invalid, as it cannot pass through a modified
endpoint anymore.
To fix this, short segments are added to link the last outline point
with an arc endpoint, but only if the distance between the two is below
a certain threshold. This way the outline is kept contiguous and the arc
end point is unmodified, warranting its correctness.
