Better time signatures

[noteflakes]

Single digit time signatures

For certain pieces, we would like to display the numerator only. With lilypond:

\once \override Staff.TimeSignature.style = #'single-digit
\time 5/4

With lydown:

\time:5/(4)

Hidden time signatures

Lilypond:

\once \override Staff.TimeSignature #'break-visibility = ##(#f #f #f) 
% or:
\once \override Staff.TimeSignature #'stencil = ##f
\time 5/4

Lydown:

\time:(5/4)

No time signature before line break

Lilypond:

\once \override Staff.TimeSignature #'break-visibility = ##(#f #t #t) 
\time 5/4

Lydown:

\time:5/4!
