bin_to_bytes
This function can turn a string of binary digits into a string of raw bytes.
For instance, "01001000" is equal to 72 in decimal, which is the ASCII/Unicode value for "H".
// Convert a string of binary digits to
// a string raw bytes spelling "HELLO"
binary = "0100100001000101010011000100110001001111";
bytes = bin_to_bytes(binary);
show_message(bytes);
NOTE: Care must be taken when using this function with GM:Studio. Unlike earlier editions of GameMaker, strings are "null-terminated" and string functions are not "binary safe". Inserting a byte with a value of zero into a string will prevent the rest of the string from being usable. Further, certain combinations of bytes may be interpreted as UTF-8 multibyte characters and results may vary on different target platforms. Storing arbitrary binary data in GM:Studio strings is NOT recommended.

- Returns a string of raw bytes (8 bits each) representing the given binary string.
