listen multiple clusters at the same time is not possible

[OscarHenry]

I'm not sure it's a bug I'm just looking for an answer to this use case, In my application (Flutter) I need to listen to several (2) clusters simultaneously and this is not possible because PusherClient is a singleton class and only allows you to pass one cluster on PusherOptions, could someone help me with some ideas on how to solve this problem?
