openEO Python client v0.7.0

Added

• Add dependency on xarray package (#159, #190, EP-3578)
• Add support for default OIDC clients advertised by backend (#192, Open-EO/openeo-api#366)
• Add support for default OIDC provider (based on provider order advertised by backend) (Open-EO/openeo-api#373)

Changed

• Eliminate development/optional dependency on openeo_udf project (#159, #190, EP-3578). Now the openEO client library itself contains the necessary classes and implementation to run UDF code locally.

Fixed

• Connection: don't send default auth headers to non-backend domains (#201)
