[NTG-context] Section numbering starting from zero, not one

[Alex Leray]

Answering my own question… this fits my needs:

###

\defineconversion[romannumeralszero][0, I, II, III, IV, V, VI, VII, 
VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XIII, XIX, XX, XXI]

\setuphead[section][conversion=romannumeralszero]

\starttext
\startsection[title={Section zero}]foo\stopsection

\startsection[title={Section 1}]bar\stopsection
\stoptext

###

Sorry for the noise
