Better error handling for authorize.
Cleaned up. Added interface for app_pins.
Little tweaks.
Updated to give better example for App PINs.
Put the verify_sign try-catch in the SDK verify sign as well. It handles bad signatures without crashing if there's a ValueError.
Added comments. Made it so app_pins are updated even on denied authorization.
Pin returns notification on Denied requests.
Logic error in is_authorized sending notification fixed. Passing tests in integrations.
