Function parse_binary 

pub fn parse_binary(n: &str) -> Vec<u8> 

Parse a string representing a binary number into a Vec.

Always use if is_binary() returns true on that string.

Examples:

use str_to_bytes::{is_binary, parse_binary};

let bin_str: &str = "0b1010001";
if is_binary(bin_str) {
    let bytes = parse_binary(bin_str);
    println!("{:?}", bytes);
}
