Add Uzbek language support

Added full Uzbek language support to Num2Words

This PR introduces comprehensive support for the Uzbek (uz) language, including:

1. Cardinal numbers — Converts integers and decimals into proper Uzbek words (e.g. 145 -> bir yuz qirq besh).
2. Currency support — Reads over 20 major currencies like USD, EUR, RUB, and UZS in Uzbek (e.g. 123.45 USD -> bir yuz yigirma uch dollar qirq besh sent).
3. Ordinal numbers — Implements to_ordinal method to convert numbers like "3 -> uchinchi, 21 -> yigirma birinchi".

This significantly improves the localization capabilities of Num2Words and adds value for Uzbek-speaking developers and applications.

Let me know if adjustments or improvements are needed. Thanks!

How to verify this change

from num2words import num2words
print(num2words(42, lang='uz'))  # qirq ikki
print(num2words(5.05, lang='uz', to='currency', currency='UZS'))  # besh soʻm, nol besh tiyin
print(num2words(2025, lang='uz', to='ordinal')) # ikki ming yigirma beshinchi

Additional notes

I decided to add this language because the number of Uzbeks in the world is now approaching 50 million. It clearly reads the numbers you enter in pure Uzbek.
