Description

This MR fixes #2365 by implementing a better way to add, and understand, WebSocket listeners + it converts kw args for PyWorker directly.

Changes

• add binaryType = 'arraybuffer' as WebSocket default
• use a better way to add listeners either as kw args or added after WebSocket creation
• convert automatically kw received for PyWorker as JS options/config
