Gpio merge for house keeping (#42)
* gpio periphery being added * gpio periphery being added * rebase gpio branch * created gpio folder and files and tests * Feature branch git action added, gpio command and constants are added * github action yml changed * testing GPIO * gpio bias keyword takenout * path typeError troubleshooting * gpio in progress #20 * disable push test until fixing the bug * Update gpio.py add all keyword args * Update gpio.py passing arguments without keyword * Update gpio.py * gpio test issue resolved #20 * working on constants
