/**
* Pads the start of a string with a given character until it reaches the specified length.
*
* If the length is less than or equal to the original string's length, or if the padding character is an empty string,
* the original string is returned unchanged.
*
* @param {string} str - The string to pad.
* @param {number} [length] - The length of the resulting string once padded.
* @param {string} [chars] - The character(s) to use for padding.
* @returns {string} - The padded string, or the original string if padding is not required.
*
* @example
* const result1 = padStart('abc', 6); // result will be ' abc'
* const result2 = padStart('abc', 6, '_-'); // result will be '_-_abc'
* const result3 = padStart('abc', 3); // result will be 'abc'
* const result4 = padStart('abc', 2); // result will be 'abc'
