// This array maps the endpoint address to a endpoint register in hardware
// By default the tinyusb stack chooses the endpoint register using the endpoint number
// However when using ISOCHRONOUS endpoints, the entire endpoint register (RX _and_ TX)
// are used for a double buffer in a single direction. If you now want to use the same endpoint number with
// different directions (e.g. 0x02 and 0x82), they would be mapped to the same register
// In this case, this serves as a crude helper to overcome this limitation by implementing
// this callback and defining a custom mapping in your application
