Function NestedNameToExtension

private/bufpkg/bufprotosource/bufprotosource.go:699–715

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