Versioning sanity checks

Utility functions to verify the expected library versions are being loaded at runtime.

The format of the returned strings are not guaranteed to remain consistent from one version to another, nor between the two functions, so please don’t try to parse them. Instead, use the macros in Version.h if you need to conditionally perform a version dependant operation.

Functions

const char * usdex::core::version()

Verify the expected usdex modules are being loaded at runtime.

bool usdex::core::withPython()

Verify whether Python support is available.
