Multisession support

[aqasemi]

Hey.

Please review this pr and tell me what do you think. I managed to make it run seamlessly with multiple devices/sessions at the same time and in one process.

No breaking changes were introduced. One can either use the regular way to create clients (with NewClient) exactly as before this PR, or with the client factory ClientFactory and it will manage clients and events by itself.

LGTM, I appreciate your pull request and you did a great job. I will merge your pull request as soon as possible.

Regarding this part:

@staticmethod
def get_all_devices(db: str) -> List["Device"]:

Could the database data be retrieved from self.database_name?

Like this:

def get_all_devices(self) -> List["Device"]:
    c_string = gocode.GetAllDevices(self.database_name).decode() 
    ...

Or, if it's better, could we rename the method to:

@staticmethod
def get_all_devices_from_db(db: str) -> List["Device"]:
    c_string = gocode.GetAllDevices(db).decode()

Then, the implementation using self.database_name would be:

def get_all_devices(self) -> List["Device"]:
    return self.get_all_devices_from_db(self.database_name)

done.
thanks for the feedback.
I preferred the latter to easily read from multiple db files.
