devine-dl/pywidevine v1.7.0 on GitHub

Ability to specify output filename by specifying a full path or a relative file name in CLI command create-device.
Add the staging privacy certificate (staging.google.com) to Cdm.staging_privacy_cert.
- Similar to common_privacy_cert which would be used on Google's production license server,
- Though this one is used on Google's staging license server (a production-ready testing server).

Raise an error if a file already exists at the output path in CLI command create-device.
Use std-lib xml instead of lxml to reduce dependencies and support ARM (#35).
Lessen restriction on Python version to any Python version >=3.7, but <4.0.
- I was hoping to do ^3.7, but some dependencies also require <4.0 therefore I cannot, for now.
Move Key ID parsing to static PSSH.parse_key_ids() method.
The shaka-packager subprocess call's return code is now returned from Cdm.decrypt().
The flags variable of a Device now defaults to a dict, even if not set.
Heavily improve initializing of protobuf objects, improving readability, typing, and linting quite a bit.
Renamed Device's _Types enum class to DeviceTypes.

Removed Device.Types class variable alias to _Types enum class as a static linter cannot recognize a class
variable as a type. Instead, the actual _Types (now named DeviceTypes) enum should be imported and used instead.

Ensure output directory exists before creating new .wvd files in CLI command create-device.
Ignore empty Key ID values in v4.0.0.0 PlayReadyHeaders.
Remove Cdm.system_id class variable as it conflicted with the cdm.system_id class instance variable of the same
name. It's also generally not needed. The same data can be gotten via Cdm.uuid.bytes.
Casting of type_ when passed a non-int value in Cdm.get_license_challenge().
Pass a PSSH object in test CLI command instead of a string.
Lower-case and setup __all__ correctly, add missing __all__ in some of the modules.
- For the longest time I thought it was __ALL__ and an iterable of objects/variables.
- However, its actually __all__ and explicitly a list of Strings...
