Not seeing any tests for this specific error, could we add?

Ditto, not seeing specific tests for this

Curious why this and the errors above had different codes previously, but now both get E_PENTAGON?

These codes were arbitrary and just indicated different return sites - they didn't really have any smenatic meaning. In h3-java, 3, 4, and 5 were all translated to the same message (essentially E_PENTAGON)

Adds consistent error returns to the gridPathCells, gridDistance, and localIj series of functions. These functions mostly already had error codes but they were not consistent with
H3Error.Changes to traversal.mdx might need to be rebased with #505.
I'm moving functions to pass int64_t when it refers to a number of cells to be consistent with
getNumCells. Would it make sense to introduce a typedef (H3NumCells?H3NumIndexes?) to avoid confusion about which type to use? Or just standardize on int64_t and let ourselves get used to that?
