Overview

This change enables the maximum frame size to be configured when receiving websocket frames. It also adds a new stream time that aggregates continuation frames together into their proper collected representation. It provides no mechanism yet for sending continuations.

I'm using the Actix Web framework in the CodeChat Editor, a text editor/word processor which renders markdown-formatted comments in source code. This is similar toJupyter, but applies to an entire programs, not just snippets of code. I use the actix-ws module to move source code between the web-based editor and the server (which is implemented in Rust). Unfortunately, the current release of the actix-ws module cannot transport source code > 64 KB over a websocket. This PR solves this problem, which is very exciting!

Is there anything I can do to support getting this PR merged? Thanks for the great work on this project!

I'll put some focus on webdockets this week. PR should be good to go as is. I appreciate the patience.
