A lot of custom logic, we basically do arithmetic on character
arrays, but this comes at with huge performance gains.
Unlike coreutils `seq`, we do this for all positive increments
(because why not), and we do not fall back to slow path if
the last parameter is in scientific notation.
Also, add some tests for empty separator, as that may catch
some corner cases.

For `od` utility, if client specifies `-N` maximum bytes to be read
then ensure stdin is left pointing to the next byte when `od` exits.
To do this...
- Bypass standard buffering on stdin.
- Instantiate BufReader further up the stack to maintain performance.
