40ed2f39a4 Make backend a required parameter in get_extractor 
Make the `backend` argument required in the `get_extractor` internal
routine. Specify a backend in the scripts which call this function. Add
a CLI backend option in capa/features/freeze.py as well.

2da2f498a2 Add script to compare vivisect Python 2 vs 3 
Compare the performance of vivisect Python 2 vs 3 by counting the number
of feature of each type extracted for every binary in `tests/data`.
Render the ones that perform bad (under a threshold - 98) and the total
performance. Render also the running time per binary for both Python 2 and 3.

From this result, it seems that vivisect behaves properly with Python3.

f9abbbe9ba hooks: change from post- to pre-commit 
Avoid erroneous commits. The pre-commit can be skipped with the
`--no-verify` option, which is not available with the post-commit.
Note that `pre-commit` doesn't run when rebase while post-commit did.

This allows to have a single script which is run by both hooks. This
scripts can also be used independently to run the CI setup locally.

8ff9e339f5 hooks: improve comment in setup-hooks.sh 
Previously the `setup-hooks.sh` took care of more things. Consequently
the comments needed to be separated. This is not needed anymore and it
looks weird.

6d00ae26ae hooks: do not repeat #!/usr/bin/env bash 
The comment claims that:
> doesn't matter if `#!/usr/bin/env bash` gets repeated later on in a hooks file

However it is a convetion that there is only one comment like that and
the `setup-hooks.sh` script already takes care of adding it if the file
didn't exist.

Alternatively, we could leave the extra comment and remove the related
code in `setup-hooks.sh`. Currently two comments are added even if the
file didn't exist.

70dda980e8 hooks: update style checkers in hooks 
Run `isort` and `black` in the hooks. Run them with the `--check` option
to not modify files which could be committed by accident.

Note that the changes in `.gitignore` are not needed as `.log` is
already excluded in the Django's section. We add those file to this
section in case `.log` is removed in the future.
