SUMMARY
Feature request: Support S3 compatible cloud storage.

OBSERVED RESULT
Currently, it is not possible to configure (or give in the URL) the endpoint URL. Hence it is _not_ possible to use kio-s3 with e.g. https://wasabi.com/. (For a list of wasabi endpoint URLs, refer to https://knowledgebase.wasabi.com/hc/en-us/articles/360015106031-What-are-the-service-URLs-for-Wasabi-s-different-storage-regions)

OBSERVED RESULT
There is no way to give endpoint URL.

EXPECTED RESULT
There is a way to give endpoint URL. This would support wasabi and other s3 compatible cloud storage. For example, this could be implemented by providing a 3-part dolphin URL scheme:

s3://ssl-endpoint-url/bucket/path 

Usage example:

s3://s3.eu-central-2.wasabisys.com/b-bucket/p-mypath
