printf-style string formatting has a number of quirks, and leads to less
readable code than using str.format calls or f-strings.
In general, prefer the newer str.format and f-strings constructs over
printf-style string formatting.
This exception takes the return value and converts that to
a human-readable string (if error string support is compiled in.)
The specialized exception is derived from WolfCryptError meaning
that existing users will not notice the difference except for the
nicer description.
* Fix some path and compiler things for Windows
* Move source code to align better with Python standards
