The codes actually JS. Ruby would look something like this, for taking the
next chunk of the bit stream:

n = Math.ceil(Math.log(charset.size) / Math.log(2))
chunk = bits[0...n]
return chunk if chunk =~ /^0/ # definitely within range
value = chunk.to_i(2)
return (value >= size.size) ? chunk[0..-2] : chunk
