re: PR https://github.com/Unidata/netcdf-c/pull/2088 re: PR https://github.com/Unidata/netcdf-c/pull/2130 replaces: https://github.com/Unidata/netcdf-c/pull/2140 Changes: * Add NCZarr-specific quantize functions to the dispatch table. * Copy (modified) quantize code from libhdf5 to NCZarr * Add quantize invocation to zvar.c * Add support for _QuantizeBitgroomNumberOfSignificantDigits and _QuantizeGranularBitgroomNumberOfSignificantDigits to ncgen. * Modify nc_test4/tst_quantize.c to allow it to be used both for hdf5 and for nczarr. * Make dap4 properly handle quantize functions in dispatch table. * Add quantize attribute support to ncgen. Other changes: * Caught and fixed some S3 problems * Fixed some nczarr fillvalue problems. * Fixed some nczarr cache problems. * Cleanup some flaws in libdispatch/dinfermodel.c * Allow byterange requests to S3 be readable by dinfermodel.c/check_file_type * Remove the libnczarr ztracedispatch code (big change).
