Capital figures need better reference in <case> feature.

Analog to adobe-fonts/source-sans#89

Possible fix:

Current:

feature case { # Case-Sensitive Forms
    sub @MARKS_CMB_ALL by @MARKS_CMB_ALL_CASE;
    sub @FIGURES_OLDSTYLE by @FIGURES_CASE;
    sub ijacute by IJacute;
    sub at by at.case;
    sub anoteleia by anoteleia.cap;
} case;

Fix:

feature case { # Case-Sensitive Forms
    sub @MARKS_CMB_ALL by @MARKS_CMB_ALL_CASE;
    sub @FIGURES_LINING by @FIGURES_CASE;
    sub @FIGURES_OLDSTYLE by @FIGURES_CASE;
    sub ijacute by IJacute;
    sub at by at.case;
    sub anoteleia by anoteleia.cap;
} case;

Alternatively, you could also move the onum feature below the case feature, and remove the line
sub @FIGURES_OLDSTYLE by @FIGURES_CASE;

Unlikely all-cap setting & oldstyle figures would interfere with each other.
