// This function is called when a packet is received on the raw HID interface.
// `length` will always be the size of the output (host to device) report in bytes - 32 in current QMK, but will eventually be raised to 64.
// Thus, if you wish to send variable length data, you should send the length along with the payload, splitting across multiple reports
// if needed, and handle the parsing yourself.
//
// In this simple example, we check that the first byte of the received data is the ASCII character 'A',
// in which case we respond with 'B' and toggle the backlight.
