Add Quenya ⟨hr⟩ and Sindarin ⟨rh⟩

Both represent a “voiceless R”, which I believe means a voiceless
alveolar trill, [r̥]. Ideally this would be one phoneme, but I’m not sure
eSpeak NG currently has a phoneme for this. The Wikipedia article [1][2]
lists occurrences in comparatively few languages, and I chose Welsh for
guidance: eSpeak NG currently turns Welsh “Rhagfyr” into [[hr'agvYr]],
and [[h]] and [[r]] are apparently just two separate phonemes, so for
now we do the same for Quenya and Sindarin, and emit hR.
