On macOS 10.15 (python3, pip3, and protobuf installed)

Used: python3 extract_android_ota_payload.py payload.bin

Got the following:

dhananjay@Dhananjays-MacBook-Air extract_android_ota_payload-master % python3 extract_android_ota_payload.py payload.bin
Traceback (most recent call last):
  File "extract_android_ota_payload.py", line 14, in <module>
    raise Exception("Python 2.x is required")
Exception: Python 2.x is required

If I simply use the inbuilt Python 2.7:

dhananjay@Dhananjays-MacBook-Air extract_android_ota_payload-master % python extract_android_ota_payload.py payload.bin 
Extracting 'LOGO.img'

Changes for python 3 have been merged (#12).

The script also require having 'bzcat' and 'xzcat' in PATH.
