fix:Unity WebGL throws Error: "ReferenceError: Runtime is not defined"

[cdle]

It seams that in unity 2021.2 variable Runtime doesn't exist and can be replaced with Module['dynCall_*'].
In webSocket.jslib change all Runtime.dynCall('*1', *2, [*3, *4]) for Module['dynCall_*1'](*2, *3, *4)

I hobbled together a somewhat hotfix version to get client reconnect working and have it work in the editor to support reconnect as well.

Would this be a good PR to consider adding to the project?

I have a working example I've tested locally and via the browser here
