Removed support for undocumented "mspythonconfig.json" config file name. This was previously available as an alternative to "pyrightconfig.json", but we've decided to standardize on the latter.
Bug Fix: Changed logic for "overload missing implementation" check to not require an implementation within a protocol class.
Enhancement: Updated typeshed stubs to latest version.
Bug Fix: Fixed confusing error message when file or directory is specified on command line but is excluded by the "exclude" section of the config file.
Behavior Change: Exempt classes from __slots__ check if they explicitly declare an empty slots. This is commonly used for mix-in classes that are compatible with slotted classes.
Internal Change: This version of pyright includes a significant change within the type evaluator that simplifies the code and eliminates a major source of bugs related to the handling of Type[X] type annotations.
