Replace argparse with configargparse and default yaml config

[paulwuertz]

Hej :)

Found some open issues and have some new ideas I would like to fix and propose to contribute over the next weekends ^^

Having a config file would be the first step, as most other stuff requires a lot of arguments.
So this could close #18

With configargparse the command line arguments can be reused in a config file.

So

./runner.py --elf_file ~/git/cannectivity/build/zephyr/zephyr.elf --build_dir ~/git/cannectivity/build/ --port 7245

is equivilent to

./runner.py -c punconfig.yaml with punconfig.yaml as

elf_file: ~/git/cannectivity/build/zephyr/zephyr.elf
build_dir: ~/git/cannectivity/build/
port: 7245

Just saw the new release of puncover, nice :)

Did a rebase for this proposal, any opinions if you agree with the configargparse package and yaml a config format?

Cheers ^^

this should either specify configargparse[yaml] or add a separate dependency on pyyaml

True, added the [yaml] extra, thanks :)
