From challange.txt

• 1087720375 | Added registry context menu for easy check from challange.txt or client_id_blob
• 1087669514 | Fixed iterating on NoneType item

• python 3.6-later compatibility
• Removed dictionary merge operator "|"
• Removed test argument. Just load the test challenge from "challenge.txt" (e.g. py check.py chalenge.txt)

• Added base64 validation
• Display if revoked or active
• Modified output file name with additional info (e.g. ChromeCDM-20122-L3-[ACTIVE].json)
• Can now load challenge base64 from txt file or client_id_blob with/without extension .bin
• Final output file path will be on the location of input file path
• And some minor changes

• Fixed matching client type
• Print device info by default. Only use quite option for client_id_blob info
• Save challenge base64 to txt file if parsing client_id_blob (so you can verify from https://tools.axinom.com/decoders/LicenseRequest)

• Added protobuf for parsing client_id_blob
• Extract challenge directly from client_id_blob file
• Fully refactored for getting/matching device info
• Added arguments (see --help)
• Display the error if found in the response

py.check.py "challenge base64 string"
py.check.py "device_client_id_blob"
py.check.py "challenge.txt"
