Dokan 2.0.0 support

[Liryna]

Dokan 2.0.0 was just released. There are a few changes in the API dokan.h and some logic described here that changed.
It would be great if the wrapper could implement those changes!
And of course, feel free to ping me if any questions or issues arise.

[DDoSolitary]

Yeah I noticed the release and will start working on this late this month (when my final exams have finished)

[Liryna]

Awesome! Take your time and good with your exams!

[FirTech]

I look forward to your support as soon

I just tested the crate, dokan2.dll is installed but indeed dokan1.dll was expected.

@DDoSolitary have you made any progress? I'm not familiar with Dokan, I've just read the docs. If you believe the changes are small between 1 and 2 and you don't have time for that, I may have a try.

I couldn't resist. PR at #5
