This module uses the FPGA_INT line present in recent Cynthion boards as a one-way communication channel. Messages or "advertisements" are sent periodically. In this commit, it will announce its intention to acquire the main USB port (CONTROL). Apollo can choose to honor this request and keep the port handed off to the FPGA until these messages stop, which is accomplished by asserting the `stop` signal or using the included `ApolloAdvertiserRequestHandler` example.

I'm happy with the functioning of this but see this comment on the corresponding Apollo PR, about how we expose this feature at the USB protocol level.
