linestyle should also accept tuples an not just strings

[JoostScheffer]

Tuples could also be used to create custom linestyles.
Example: https://matplotlib.org/stable/gallery/lines_bars_and_markers/linestyles.html

Currently linestyle is a TextWidget. But since tuples are passed as tuples and not as text, this is incompatible.
I don't yet have an idea of a good modular way to implementing this would be.
Creating a custom function in the TextWidget could be possible...

Any suggestions?

well pylustrator could try to convert the text into a tuple and if it fails then use it as text.
