lib: change `ord()` to always return single byte value

The most common usecase is extracting the value of a single byte at a
specific offset, e.g. to scan a string char-by-char to construct a hash.

Furthermore, constructing an array which contains the results of multiple
`ord()` invocations is trivial while efficiently extracting a single byte
value without the overhead of an intermediate array is not.

Due to that, change `ord()` to always return a single integer byte value
at the offset specified as second argument or at offset 0 in case no
argument was supplied.

That means that `ord("Abc", 0, 1, 2)` will now return `65` instead of the
former `[ 65, 98, 99 ]` result.

Code relying on the former behaviour should either perform multiple calls
to `ord()`, passing different offsets each time or switch to the `struct`
module which allows efficient unpacking of string data.
