feat: support ksp bundling

[lucaseck]

What was the problem/requirement? (What/Why)

There was no pathmapping support with KeyShot.

What was the solution? (How)

One way around this is to bundle a scene up as a KeyShot Package(ksp) which creates a zipped archive of the scene file and any external file references. The scene within is modified to have relative paths to all of the referenced files.

This PR adds a submission mode selector for:

1. Just submit the scene .bip file and all files referenced within will have to be available through network storage or some other means
2. Automatically save the current scene as a ksp to a temp directory, unpack it and then submit the modified scene and assets from the unpacked ksp where all paths are relative

What is the impact of this change?

KeyShot can be used without having to deal with manually packing/unpacking ksps or setting up network storage

How was this change tested?

• Ran all unit tests including newly included ones
• Ran submissions using both submission modes and verified the outputs
• Tested canceling the dialog, and the sticky setting of which option was selected

Was this change documented?

Only in the README

Is this a breaking change?

No
