Sine Wave Sender/Receiver

Run the receiver in one terminal:

yarn example:receiver

Run the sender in another terminal:

yarn example:sender

Both examples use universe 1, the test K0/TUID constants, and the folded multicast address for that universe. If your OS needs an explicit multicast interface for receive, set SIGNET_IFACE, for example:

SIGNET_IFACE=192.168.1.20 yarn example:receiver
