[NTG-context] enumeration with the Spanish alphabet

Hans, enumerating using the Spanish alphabet lacks a letter between n and o, the ñ. Here is the small sample that shows the missing letter: \mainlanguage[es] \starttext \startitemize[a] \dorecurse{30}{\item \recurselevel} \stopitemize \stoptext Instead of changing the default letter series, how about adding the ñ (or Ñ) after n and before o (or after N and before O) in a new enumeration series named ñ (and Ñ). This is the correct way to enumerate with letters in Spanish (and this is used in legislation, such as in https://www.boe.es/buscar/act.php?id=BOE-A-1992-28741#a49).
