SYNOPSIS
result = string.byterevert(s [, i [, j]])
DESCRIPTION
Reverses the order of bits in each byte of the string. The order of bytes in the string is not changed.
When i and/or j are given, uses the substring s[i],
s[i+1], ···, s[j].
The default value for i is 1;
the default value for j is the number of characters in s.
RETURN VALUE
A string with the bits of each byte reversed. The result has the same length as the original substring.
