* Replace wholevar with more useful wholechunk optimization * Add optimization to read multiple values at one time * Replace NCDEFAULT_get/put_vars with native nczarr versions. * Clarify chunk projection computations * zdebdispatch.h * Add more chunking test cases and re-enable run_chunkcases * If !szip, then suppress deflate interference test * Make H5Znoop(1) filter produce more information * cleanup bzlib.c API
