Function NestedNameToEnum

private/bufpkg/bufprotosource/bufprotosource.go:675–691

NestedNameToEnum maps the Enums in the ContainerDescriptor to a map from nested name to Enum. Returns error if Enums do not have unique nested names within the ContainerDescriptor, which should generally never happen for properly-formed ContainerDescriptors.
