Syntax: decode_binary (STR bin-string [, fully]) => LIST
Returns a list of strings and/or integers representing the bytes in the binary string <bin-string> in order. If <fully> is false or omitted, the list contains an integer only for each non-printing, non-space byte; all other characters are grouped into the longest possible contiguous substrings. If <fully> is proved and true, the list contains only integers, one for each byte represented in <bin-string>. Raises E_INVARG if <bin-string> is not a properly-formed binary string. (See the LambdaMOO programmer's manual on MOO value types for a full description of binary strings.)
