[Pycrc-users] type mismatches solved

[C. M. <cm...@gm...>]

I have not fully validated the results, but casting the return value of
crc_reflect() to crc_t seems to give good results (not just quiet the
compiler).

I was a little surprised that all my crc's were coming back zero until I
realized I forgot to initialize the table!

It would be nice to update the example at the end of the man page now that
the most functions require a pointer to a crc_config_t.

Thank you very much!
