cad/openvsp: update to 3.35.2
ChangeLog: https://github.com/OpenVSP/OpenVSP/releases/tag/OpenVSP_3.35.2
Quick fix to prevent inf and nan values from propagating to delabella
where they can cause a crash.
These inf values likely come from the tri-tri intersection code. Fixing
them there would be preferable, but this remains a reasonable safeguard.
