Monospaced / Tabular figures in LilyPond

[Karol Majewski]

In some fonts default spacing format for figures is set to proportional, which 
means that numerals have variable spacing - depending on glyph width. I'd like 
to change the format to tabular, so that numerals are monospaced. This is 
typical OpenType feature. In XeLaTeX I can do this via:

\usepackage{fontspec}
\setmainfont [Numbers = {Monospaced}]{Fontname}

How can I achieve this in LilyPond?
