Update dependencies.

[HolonProduction]

When installing gdtoolkit one gets prompted with a warning about deprecated installation methods. Starting from pip 23.1 (we are currently at 23.0) a special flag will be needed to install the package. The warning is caused by two packages in the dependencies.

• future which is in fact a dependency of radon. The future package is a python 2 polyfill and was already removed from the radon project. The change was not yet released but hopefully New release to drop future package rubik/radon#238 will get a response soon. So no action is needed for the moment.
• The second warning comes from the docopt package. It has seen its last release on PiPy in 2014. The package is basically unmaintained and will see no further releases. According Is python-docopt still under maintenance? docopt/docopt#494 docopt-ng is the new maintained version of the package. It already uses the new setup process and can be used to as a drop-in replacement.

Also I don't see a reason for keeping lark at a fixed version. Is there any?

Sounds good, I'll take a look into it.

Regarding lark dependency, in the past, they've introduced major breaking changes between releases that broke gdtoolkit so I don't trust them anymore and therefore I prefer to update lark dependency manually.

Seems fair. Having a look at their release history I would suspect that breaking changes were only introduced with the 1.0 update. After that they list no compat changes (there may be some smaller stuff). I guess I will give the upgrade a try when I find some time.
