ZARR: aborted create leaves directory and files

[mdsumner]

What is the bug?

I think an error like "Invalid number of values in BLOCKSIZE" should clean up the empty directories left behind.

I encountered this by switching from a multiband PNG BLOCKSIZE=4,4,5 to a single band TIF BLOCKSIZE=1,128,256 naively thinking in degenerate dimension terms.

Steps to reproduce the issue

gdal_translate  gdrivers/data/png/byte_with_xmp.png  fail.zarr -of ZARR -co BLOCKSIZE=1,4,4
ERROR 1: Invalid number of values in BLOCKSIZE

we now have leftover to clean up:

fail.zarr/
fail.zarr/.zmetadata
fail.zarr/fail
fail.zarr/.zgroup
