Dicomweb-client

New features
Add support for client SSL certificates

Bug fixes

* Remove "boundary" in multipart/related accept header field, which broke compatibility with DCM4CHEE.

API changes

- rename `DICOMWebClient` class to `DICOMwebClient` for consistency with client implementations in other languages (e.g., JavaScript [dcmjs-org/dicomweb-client](https://github.com/dcmjs-org/dicomweb-client))

New features

- add parameters to `DICOMwebClient` class constructor to specify URL path prefix for different RESTful services (QIDO-RS, WADO-RS, STOW-RS) - this allows using the same client instance across services even if they have different locations

Add boundary to multipart messages

- Support for additional MIME types, such as `image/jp2`
- Bulkdata are returned as raw bytes instead of Pillow `Image` objects

Renamed QIDO-RS methods of `DICOMWebClient` class
