Expose WebSocket settings before open a PusherSDK Connection

[GDGRhinox]

Description

When using the PusherSDK on a Unity .NET project, the WebSocket is created using a Unity Mono backend instead of standard .NET. Using Unity Mono websockets prevents us from connecting to a standard soketi setup of a Pusher server.

This is because the default WebSocket gets rejected and furthermore the current settings do not allow a self-signed certificate to be used. This change introduces an event which allows users of the PusherSDK to receive an event before a WebSocket connection is opened, thus allowing them to modify the supported TLS version and add custom certificates.

CHANGELOG

• [ADDED] Create a public static ConnectionEvents.OnPostWebSocketCreate event which gets called after a WebSocket is created and before the connection is opened, allowing end-users to edit specific connection settings (such as security).
• [CHANGED] Refactored the creation of WebSocket in separate method that calls the ConnectionEvents.OnPostWebSocketCreate event

Still using a local edited built instead of an official release to handle this issue internally, this issue affects other users as well as I have read on Unity user forums. Thus fixing it upstream would be preferable.
