set_reserved_function_config() method for HiSockClient and HiSockServer

[SSS-Says-Snek]

Is your feature request related to a problem? Please describe.
When I saw sheepy use hisock, he used his implementation of the leave reserved function, because he sent some extra data. So, I realized that the functions would be useless to people who want to have their custom data sent on a particular reserved function event.

Describe the solution you'd like
So, I plan to add this method so that users can specify the data they want to send whenever a reserved function is triggered. The usage would probably be like server.set_reserved_function_config('leave', ['clt_info', 'my_data', 'more_data'])

whaddya think @sheepy0125

[sheepy0125]

It sounds cool!

Will this allow for multiple arguments being passed into a function? Can I make my own custom reserved function?
Something like:

server.set_reserved_function_config("create_sheep", ["client_info", "sheep_breed", "sheep_age", "sheep_mass"])

@SSS-Says-Snek.on("create_sheep")
def create_sheep(client_info, sheep_breed, sheep_age, sheep_mass):
   ...

1. yes, that's basically the point of the function; to provide extra data when a reserved function is called
2. I don't think so, since hisock won't know when to call your "created reserved function" (given that when you mean "custom reserved function", you want hisock to call it on a new custom event

I might be able to program something that allows you to create custom events though, but first I'll need to implement this :kekw:
