JIFFY[257] - Fix: Use NumberFormat for locale-aware numeral parsing

[jama5262]

What does this PR do?

Jiffy was failing to parse numbers in locales that use non-standard numerals (e.g., Bengali, Arabic, etc.). For example, when retrieving the day of the year, it might return ৭৮ (Bengali for 78), but Jiffy would attempt to parse it as an integer and fail.

Solution

Used NumberFormat from the Intl package to correctly convert locale-specific numerals to standard numerals.

This ensures that Jiffy can properly handle numbers from different locales without parsing errors.
