Is your feature request related to a problem?

I want to sort the channel list by something other than what we can currently sort by (last_updated, last_message_at, updated_at, created_at or member_count).

In my case, I want to include the channel type in the sort function so certain chanel types are always on the top

Describe the solution that you'd like

A parameter on StreamChannelListController which allows setting a comparison function to determine the order of channels.

eg:
customSortFunction: bool Function(Channel, Channel)?

Describe alternatives that you have considered

I can't see how I can do what I wanted wit these new changes. Looks like I am still limited by string values for the sort options (eg. last_message_at) but I don't think it's possible to sort channels by channel type which is the use case I mentioned in this issue.
