Argument String becomes Integer because of numeric data

[YigitBurdurlu]

A simple argument is automatically converted to integer because the input only has numeric data in a string. I wondered if it is a wanted feature. Thank you

Python3 version = Pyton3.8.10 Fire version = 0.5

0 <class 'int'>

Expected behavior: "00" string type
