Description

When I cast a string with prefixed 0 like "0123" with cast.ToInt("0123"), it results into 83 instead of the expected 123

Example code:

package main

import (
	"fmt"
	"github.com/spf13/cast"
)

func main() {
	numb := "0123"
	castedNumb := cast.ToInt(t)
	fmt.Println(numb, castedNumb)
}

Research direction

Reproduce the reported behavior through the cast.ToInt entry point using the "0123" example, then inspect the conversion path it uses for numeric strings. Done means the conversion returns 123 rather than 83 while preserving the expected behavior for other supported integer inputs.
