Seppe Stas 264315ab81 Fix markdown and format of GPIO example README
Fixed headers so they work (requires space between hash and text) and have a sensible structure and removed trailing spaces.

# Example: GPIO
This test code shows how to configure gpio and how to use gpio interrupt.
## GPIO functions:
* GPIO18: output
* GPIO19: output
* GPIO4: input, pulled up, interrupt from rising edge and falling edge
* GPIO5: input, pulled up, interrupt from rising edge.
## Test:
* Connect GPIO18 with GPIO4
* Connect GPIO19 with GPIO5
* Generate pulses on GPIO18/19, that triggers interrupt on GPIO4/5
