Returns the script for a given Locale.
If the locale isn't already in its maximal form, likely subtags for the provided locale
ID are added before we determine the script. For further details, see the following CLDR
technical report :
http://www.unicode.org/reports/tr35/#Likely_Subtags
If locale is already in the maximal form, or there is no data available for maximization,
it will be just returned. For example, "und-Zzzz" cannot be maximized, since there is no
reasonable maximization.
Examples:
"en" maximizes to "en_Latn_US"
"de" maximizes to "de_Latn_US"
"sr" maximizes to "sr_Cyrl_RS"
"sh" maximizes to "sr_Latn_RS" (Note this will not reverse.)
"zh_Hani" maximizes to "zh_Hans_CN" (Note this will not reverse.)
