update pyshark to ^0.4.4

[shred2]

Hi!

when installing poetry install on ubuntu 21.04, I had a problem with resolving pyshark. With a poetry update pyshark to the latest 0.4.4, the problems go away.

Would you like to have this change?

(btw, I do not know why poetry re-sorted the poetry.lock file. I am on poetry version 1.1.8. If I should upgrade for a better result, let me know.)

Don't worry about poetry.lock's order, I usually work on poetry workflows and I've come to the conclussion that you need to trust the tool and the tests 😃

Thanks a lot, I need to have a look at pyshark's release policy, It might be better to just set it as "^0.4"
