audio/celt: Added (low delay audio codec)

+CELT is a very low delay audio codec designed for high-quality
+communications. Traditional full-bandwidth  codecs such as Vorbis and
+AAC can offer high quality but they require codec delays of hundreds
+of milliseconds, which makes them unsuitable  for real-time
+interactive applications like teleconferencing. Speech targeted
+codecs, such as Speex or G.722, have lower 20-40ms delays but their
+speech focus and limited sampling rates restricts their quality,
+especially for music.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
