Added/Fixed Typing for all files in vunit.ui package

No description provided.

Suggested change

	from vunit.design_unit import DesignUnit
	from vunit.design_unit import DesignUnit

Not sure if any linting rules are applied, but this seems to make more sense either way.

[g0t00]

I do not really catch what your saying. But I did not find clear style re: import statements.
Also after doing all the changes I realized that vunit uses relative imports for most/all internal imports.
I personally do not like relative imports in python, but for consistencies sake I would change. If somebody from the core team can pitch in...

[oscargus]

Sorry for being unclear, the point was that if there is an empty line, it should probably not happen between the vunit imports.

Now

from typing...
from vunit...

from vunit...

Better

from typing...

from vunit...
from vunit...

(Tools like isort would probably have done something like the latter anyway.)

[g0t00]

Ah yes, thank you. Totally agreed.

(normally I just let isort handle imports)

Typing always helps! Some minor comments (I have no powers to approve or merge or whatever, but for what it is worth).

Furthermore:

• Please add a news fragment to docs/news.d/. See vunit.github.io > Contributing > Release Notes Instructions and towncrier.readthedocs.io > Tutorial > Creating News Fragments.
• Does mypy support specifying config options in pyproject.toml instead of using a separated file (mypy.ini)?
