Sentinelhub

- Improved documentation for Copernicus Data Space Ecosystem.
- Restrict numpy version to <2 in anticipation of numpy 2.0 release.

This update ensures that [session-sharing](https://github.com/sentinel-hub/sentinelhub-py/blob/master/examples/session_sharing.ipynb) works as intended.

Changelog:

- Adjust session caching to mirror changes to the core services. Older version might no longer correctly cache sessions.
- Switch default auth endpoint to the new address.

- The `SentinelHubDownloadClient` class now has a `default_retry_time` parameter, which allows control over the waiting time when a request gets a 429 TOO_MANY_REQUESTS response without a specific retry time in the headers. The default value for this behavior has been changed from 0s to 30s to avoid edge-cases where SH services were bombarded with requests.

- Fixed a problem with `dataclasses_json 0.6.2` that broke BYOC functionalities
- Removed AWS examples from the docs since the functionality is no longer maintained.

Changelog:

- `SHConfig` now correctly initializes a default profile in the file even if the first initialization call is done with a custom profile.
- Save and load methods of `SHConfig` adjusted to work with the environmental variable `SH_PROFILE`
- CLI command `sentinelhub.config --show` works with the environmental variable `SH_PROFILE`

Changelog:

- Adjusted how user credentials are passed to the OAuth service.
- Added `QUALITY_FLAGS` band to `S3_OLCI`
- Batch statistical API now supports IAM role style credentials.
- Various minor improvements
