get slot for use with local 1D coordinate arrays

### Synopsis

    PETSC_EXTERN PetscErrorCode DMStagGet1dCoordinateLocationSlot(DM dm,DMStagStencilLocation loc,PetscInt *slot)

High-level helper function to get slot ids for 1D coordinate DMs. For use with DMStagGetIDCoordinateArraysDOFRead() and related functions.

Not Collective

### Input Parameters

| dm | - the DMStag object
| loc | - the grid location

### Output Parameter

slot -the index to use in local arrays

### Notes

Checks that the coordinates are actually set up so that using the slots from the first 1d coordinate sub-DM is valid for all the 1D coordinate sub-DMs.
