…ensions Periphery incorrectly reported subscript(dynamicMember:) as unused when declared in an extension of an external type with @dynamicMemberLookup (e.g., Foundation's AttributeDynamicLookup). The fix retains all subscript(dynamicMember:) declarations unconditionally, since this signature is specific to Swift's @dynamicMemberLookup mechanism. Fixes peripheryapp#1066
