Bravura classes not listed in spec

[knutnergaard]

Bravura has a number of classes not listed in the SMuFL specification:

figuredBass
tf_chordSymbolAccidentals
tf_chordSymbols
tf_daseianNotation
tf_figuredBass
tf_hairpins
tf_harpPedals
tf_metronomeMarks
tf_ornaments
tf_pedals
tf_pictograms
tf_prolations
tf_zeroWidth

Given Bravura's reference font status, I would suggest adding them.
