Modify version number to match the Gelly version for each compile

[yogwoggf]

Context

Using rcedit, we can actually modify the nifty little version metadata found in most professional binaries (dll/exe) files for real software. rcedit is also heavily self-contained and has prebuilt binaries ready.

Scope

• Add code to the CMakeLists.txt to modify the resulting binary if rcedit is on the path
  • I think we should do this as a cache variable
  • Would make it easier for the CI/CD pipeline
• After each compile, the build will modify the resulting binary with the current GELLY_VERSION.

Acceptance Criteria

• Binaries, if possible, have their Gelly version attached
