Configures the total fuel calculation to use GPIO inputs.

n = 1 to 6	GPIO used (Default 1)
x = 0 to 10	GPIO reading at empty (current or voltage) (Default 0)
y = 0 to 10	GPIO reading at full (current or voltage) (Default 100)
z = 1 to 65535	Number of liters required to reach full (Default 50)

Notes:

Examples:

Use input 1, 0V input when empty, 10V when full and a full tank taking 100 Liters :
cmd fuel io 1 0 10 100
