Moved OpenVSP version check to fix API docs

[sseraj]

Purpose

198 broke the API docs for DVGeometryVSP, the modules that follow it in __init__.py (DVGeometryESP, DVGeometryMulti), and the MPhys wrapper. The problem is that the openvsp.GetVSPVersion() call occurs outside the class, which does not work when we have mock imports for the doc build. To fix this, I moved the version check into the __init__ function.

@sseraj there is a unit test for the out of date features, but can you expand it to check the different version conditions? I think the machinery is there to do it fairly easily.

I don't think there is a good way of doing this with a dummy OpenVSP module. The other version conditions don't raise an error, so the entire __init__ function runs when I try to test it. To properly test multiple versions of OpenVSP, we would have to set different stable and latest versions in our Docker images.

Okay, I guess it's fine. We're throwing a descriptive error message about the version so the user will be made aware of the problem.
