healpix.py: Implement "ang2pix_ring" and "pix2ang_ring" with JIT
To optimize "map_grid_to_healpix()" in `grid.py` which uses
"healpy.ang2pix()" using `numba.jit`, implement the latter's
functionality explicitly with `numba.jit` support.
The implementation simply mimic the corresponding functions
"ang2pix_ring_z_phi()" and "pix2ang_ring_z_phi()" in HEALPix's
"src/C/subs/chealpix.c". Thanks!
