Firstly, I want to remove the Message structure in model to avoid unnecessary memory allocation in into_message, and also simplify the whole process. This will not be a breaking change because user don't really use this structure.

Update: We didn't support progess token in previous version, but we had to handle this now, because we should figure out the corresponded request id for progress notification now.

@4t145 I would love to help out. How can I assist in supporting the latest revision?

[4t145]

@dbettin I plan to merge #84 firstly and then implement streamable http transport and authorization. Works in #84 are almost done. If you have a good implementation for streamable http transport, you can post it so we can have a discussion on it.

I will add the oauth support.
