start.sh uses deprecated GPIO interface for reset

[octal-ip]

The start.sh script uses a deprecated method of toggling GPIOs to reset the iC880a. This no longer works on current versions of Debian (bookworm) - it causes error messages to be shown, and the RAK5146 PiHAT module will not operate.

I suggest replacing lines 6 through 14 with the following, which resolves the problem:

gpioset gpiochip0 $SX1301_RESET_BCM_PIN=0
sleep 0.1
gpioset gpiochip0 $SX1301_RESET_BCM_PIN=1
sleep 0.1
gpioset gpiochip0 $SX1301_RESET_BCM_PIN=0
sleep 0.1

Edit: I've found that https://github.com/RAKWireless/rak_common_for_gateway/blob/master/lora/rak5146/reset_lgw.sh has the same problem.
