[settings] Add "hexhyp" setting type
Provide a "hexhyp" setting type, which functions identically to the
"hex" setting type except that it uses a hyphen instead of a colon as
the byte delimiter.
For example, if ${mac} expands to "52:54:00:12:34:56", then
${mac:hexhyp} will expand to "52-54-00-12-34-56".
