pre-commit has been added to the GitHub Actions workflow in this repository. pre-commit allows you to run multiple checks, such as black and checking the REUSE licensing compliance, both locally and on GitHub Actions with one command.

You can run pre-commit locally with `pre-commit run --all-files`

fingerprint_r503_rpi.py example updated to use the correct image size when downloading the fingerprint image.
The r503 has a 192x192 image. the other sensors use 256x288.

Adds a function set_led() to the library to control the built-in LED for the r503 sensor.


def set_led(self, color=1, mode=3, speed=0x80, cycles=0):
"""LED function -- only for R503 Sensor.
Parameters: See User Manual for full details
color: 1=red, 2=blue, 3=purple
mode: 1-breathe, 2-flash, 3-on, 4-off, 5-fade_on, 6-fade-off
speed: animation speed 0-255
cycles: numbe of time to repeat 0=infinite or 1-255
Returns the packet error code or success"""

Added examples for r503 that demonstrate some led functions.

Details regarding the LED control are in the Users Manual

Added finger_search() function and modified examples to use it instead of finger_fast_search().
The finger_fast_search does not work on the R503 Panel Mount Fingerprint Sensor.
Modified the examples to use finger_search() so they work with both the R503 Panel Mount FingerPrint Sensor (PID 4651) as well as the Fingerprint Sensor (PID 751).
Also added access to attributes for "system_id" and "status_register".
