As discussed in a netcdf meeting, convert NCZarr V2 to store all netcdf-4 specific info as attributes. This improves interoperability with other Zarr implementations by no longer using non-standard keys. ## Other Changes * Remove support for older NCZarr formats. * Update anonymous dimension naming * Begin the process of fixing the -Wconversion and -Wsign-compare warnings in libnczarr, nczarr_test, and v3_nczarr_test. * Update docs/nczarr.md * Rebuild using the .y and .l files
