[OSX] libftdi include <ftdi.h> compilation error

[Derek Olson]

Cannot compile library on osx due to the library not using the correct libftdi1 include path. I believe this is due to the generated config.h file being included after the mpsse.h include here: https://github.com/l29ah/libmpsse/blob/master/src/mpsse.c#L15

Would it make sense to instead include the config.h defines within mpsse.h since it is used amongst many parts of this library?
