Feature Request: Watchers in Bulk Query Channels

[DsMaccy]

High Level Description

The apiClient.queryChannelsRequest method does not provide watchers. The lack of watcher data limits the usability of the bulk query channels endpoint and requires a backend change. Without this data, we are forced to query the channels one at a time.

What I've Tried

1. I have attempted to use the queryChannel by ID functionality which provides the appropriate data with the watcher pagination options. This works but runs into a rate limit
2. I have tried using the queryChannelsRequest endpoint and tried forcibly injecting the watcher_limit and watcher within the ChannelOptions while ignoring the type errors.
3. I have tried setting presence to true and also tried setting watch to false on the queryChannelsRequest input

Suggested Fix

The suggested fix has multiple parts:

1. Add an input option for watcher_limit on the bulk channels endpoint
2. Introduce a watcher_limit on the ChannelOptions type in the SDK client and port the appropriate data through (my personal use-case is in node):

export type ChannelOptions = {
  limit?: number;
  member_limit?: number;
  message_limit?: number;
  offset?: number;
  presence?: boolean;
  state?: boolean;
  user_id?: string;
  watch?: boolean;
  watcher_limit?: number;
};
