Bug Fixes

• In Swift 5.3 and lower, all optional protocol members are now retained in order to workaround a Swift bug. This bug is resolved in Swift 5.4.
• Cases of public enums are now also retained when using --retain-public.
• Open method parameters are now also retained when using --retain-public.
• Empty public protocols that have an implementation in extensions are no longer identified as redundant.
• Foreign protocol method parameters are no longer identified as unused.
