This PR allows duplicate dimension when chunking an array, when the chunk sizes is provided as a dict.
A typical example of the usefulness of this PR is trying to open a netcdf file (with chunking) containing a covariance matrix.
.chunkfor datasets with duplicated dimension names, e.g. Sentinel-3 OLCI files #8579, closes olci_l1b-reader and xarray=2023.12.0 are seemingly incompatible pytroll/satpy#2705, xref Many methods are broken (e.g., concat/stack/sortby) when using repeated dimension names #1378whats-new.rst
