FreeBSD Port

Hi there,

I just added a FreeBSD port including an rc-file. I'll keep maintaining
and updating it. Once the package building pipelines processed the
packages, one will be able to install unpackerr on FreeBSD simply by
running

pkg install unpackerr

Feel free to update the documentation :)

And keep up the good work!
