feat: remove vendored dependency prettytable

[fpgmaas]

Currently, the project has prettytable as a vendored dependency. This seems superfluous, we can add it as a regular dependency.

While it is out of the scope of the PR, may we create and start filling the NOTICE file? We need to do it sooner or later anyway. Let's include this notice (about binary, because we are using it as whl from PyPI) to NOTICE-binary.md? What do you think @fpgmaas ?

That is an example of NOTICE-binary.md in Spark itself.

I am not familiar with that file @SemyonSinchenko . Shall we leave that for a separate PR, since it seems unrelated?

Yes we can postpone it. Leave it on me.
