 * Takes a user-authorable string with several whitespace delimited arguments and builds a byte array
 * from it. Arguments can be hex data/numerals, decimal numbers or ASCII strings. Literals are padded
 * to 32 bytes if prefixed by a '@' (or not prefixed at all), and tightly packed if prefixed by a '$'.
 * Currency multipliers can be provided.
 *
 * Example:
 * @code
 * parseData("$42 0x42 $\"Hello\"");	// == bytes(1, 0x2a) + bytes(31, 0) + bytes(1, 0x42) + asBytes("Hello");
 * @endcode
