EOPF Zarr backend for xarray

An xarray backend implementation for ESA EOPF data products in Zarr format.

After installing this package, user can specify a new xarray backend named `"eopf-zarr"` to open EOPF sample products. The backend has two modes of operation, default analysis mode and the native mode. Both modes allow

 * to open EOPF sample products from the local filesystem or from
   their original object storage using URLs with both `https` or `s3`
   protocols;
 * to open entire products as `xarray.DataTree` or `xarray.Dataset`;
 * to open a subgroup as `xarray.Dataset`. This works with
   local filesystem or `s3`-URLs.

The default analysis mode has the aim to represent the EOPF data products in an analysis-ready and convenient way. It provides the following features:

 * Open the deeply nested EOPF products as flat `xarray.Dataset`
   objects.
 * All bands and quality images resampled to a single, user provided
   resolution, hence, spatial dimensions will be just `x` and `y`.
 * User-specified resampling by passing interpolation methods for
   up-scaling and aggregation methods for downscaling.
 * CF-compliant spatial referencing of datasets using a shared grid
   mapping variable `spatial_ref`.
 * Attach other CF-compliant metadata enhancements such as flag values
   and meanings for pixel quality information, such as the Sentinel-2
   scene classification (variable `scl`).

The native mode does not modify any contents or data, instead it basically delegates to the built-in `zarr` backend.
