Update documentation

[ehaupt]

Update documentation:

• Add FreeBSD to the list of tested versions
• Add a nice repology badge to show the packaging status of this project

After merging #171, I've added an official FreeBSD port to the repository. I've tested the python bindings as well as the pactester binary. Here is how a FreeBSD user can install pacparser.

Via package:

pkg install pacparser

Building via ports:

cd /usr/ports/www/pacparser
make install clean

I had to reference the latest commit hash for the version since earlier releases didn't have FreeBSD support. Please consider tagging v1.4.3.

Tests

pactester:

# uname -a
FreeBSD portjail.local 13.2-RELEASE-p1 FreeBSD 13.2-RELEASE-p1 GENERIC amd64
# gmake testpactester
echo "Running tests for pactester."
Running tests for pactester.
NO_INTERNET= ../tests/runtests.sh
All tests were successful.

Python bindings:

# python ../tests/runtests.py 
Build dir: %s /usr/ports/www/pacparser/work/pacparser-e29c1a3/src/../tests/../src/pymod/build
['lib.freebsd-13.2-RELEASE-p1-amd64-cpython-39', 'temp.freebsd-13.2-RELEASE-p1-amd64-cpython-39']
All tests were successful.
