[Bug] i.sentinel.download: Support Copernicus Data Space Ecosystem Service

[ninsbl]

i.sentinel.download

Describe the bug
ESA will discontinue data provision through DHUS software and scihub.copernicus.eu (see: https://scihub.copernicus.eu/):

The Copernicus Data Hub distribution service will continue its full operations until the end of June 2023 to allow a smooth migration to the new Copernicus Data Space Ecosystem by all user communities. As from July 2023 and until September 2023, the Copernicus Data Hub distribution service will continue offering access to Sentinel data with a gradual ramp-down of the operations capacity and data offering.

The sentinelsat library used in i.sentinel.download seems unfortunately not yet compatibel with the new Copernicus Data Space Ecosystem Service (se: sentinelsat/sentinelsat#583).

However, [eodag]( (https://github.com/CS-SI/eodag/releases/tag/v2.9.1) and creodias-finder libraries already seem to handle the new Copernicus Data Space Ecosystem Service API.

eodag seems more versatile as it may also be useful for Landsat (#830), while creodias-finder seems more lightweight...

In any case. i.sentinel.download will stop working with scihub latest september 2023., so a replacement is needed..

Starting april 2023, data delivery with STAC is planned for the Copernicus Data Space Ecosystem ... (so, #802 may become relevant too)...
