Mapping Unicode script name to CLDR script code

[Kip Cole]

Using the script properties (from scripts.txt in the Unicode repo for example), the script of some text can be detected. 

However I am not able to find a mapping from Unicode script names to CLDR script codes.  Ie a way to map "Hirigana -> Jpan" or "Javanese -> Java".

I’ve checked supplementalData.xml and scriptMetadata.txt to no avail.

Is there a canonical mapping somewhere?

Many thanks, —Kip
