Serializing from borrowed TypedReader

[marmeladema]

Hello,

I happen to face a situation where in some API I have a borrowed TypedReader and I need to serialize it.

I might have missed something, but it seems to serialize from a reader, I need access to the ReaderSegments which I can only obtain by doing typed_reader.into_inner().into_segments() which is consuming the input TypedReader.
However the serializing functions (the _to_words ones) actually accept a borrowed ReaderSegments.

Is there a reason for not exposing a borrowed ReaderSegments?
If we added a method like get_reader_segments(&self) -> &S it should fix my issue.

Thank you for your help.

Adding a message::Reader::get_segments() method makes sense to me.

Okay I'll try to open a PR soon :-)
