core/room: add channel manager, fix bug where channel options not applied

[AndyTWF]

Context

Closes #411
CHA-738.

Description

This change fixes the bug described in #411 whereby channel options are overwritten by successive uses of the same channel, rather than merged together.

In doing this, we also fix the bug in relation to newly introduce spec point CHA-RC3. We were previously depending on the soft-deprecated behaviour in RTS3c which would allow you to update channel options via setOptions.

The change is achieved by adding a channel manager, whose job it is to register all the options for a given channel prior to the first channels.get() call, and call channels.get with the amalgamated options.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
