OSCreceive signals does not emit signals under some circumstances

[djiamnot]

As mentioned in 11744aa, OSCreceive will not emit osc_message_received signal unless either set_process(true) was called at _ready() (or some other such time).
Moreover, we get ERROR: emit_signal: Error calling method from signal 'osc_message_received': 'NodeName(AttachedScript.gd)::_on_custom_method_osc_message_received': Method not found. if _process(delta) is present but unset.

Here's a small project that documents a workaround to correctly send and receive OSC.
