CAPEv2 dependency issue

[federicofantini]

Poetry error:

Because malduck (4.3.1) @ git+https://github.com/CERT-Polska/malduck/@HEAD depends on dnfile (0.11.0)
 and capev2 depends on dnfile (0.13.0), malduck is forbidden.
So, because capev2 depends on malduck (4.3.1) @ git+https://github.com/CERT-Polska/malduck/, version solving failed.

Pip3 error

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
flare-capa 5.0.0 requires dnfile==0.13.0, but you have dnfile 0.11.0 which is incompatible.

possible solution: update requirements.txt: dnfile==0.11.0 -> dnfile==0.11.0
