  basically do whatever you want with this code.

  This example configures the High Navigation Rate on the NEO-M8U and then
  polls and displays the attitude solution, vehicle dynamics information
  and high rate position, velocity and time.
  
  This example polls the high rate data.
  (The next example uses "autoHNR" to receive the HNR data automatically.)
  
  Please make sure your NEO-M8U is running UDR firmware >= 1.31. Please update using u-center if necessary:

  Hardware Connections:
  Plug a Qwiic cable into the GPS and a Redboard Qwiic
  If you don't have a platform with a Qwiic connection use the 
	SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
  Open the serial monitor at 115200 baud to see the output
