A factory function to construct an object of type TpuConnection.
The returned connection object should not be used directly; instead it should be passed as an argument to the constructor of TpuClient.
The optional options argument may be used to configure aspects of the returned TpuConnection. Expected options are any of the types in the following option lists:
