Some zener models are unusable

[fedorkotov]

Some subcirquits in https://github.com/kicad-spice-library/KiCad-Spice-Library/blob/master/Models/Diode/zener.lib library have missing .ENDS cards and DR models. For example these ones:

• DI_BZX84C3V6T
• DI_BZX84C3V6TS
• DI_BZX84C3V6W
• DI_BZX84C3V9S
• DI_BZX84C3V9T
• DI_BZX84C3V9TS
• DI_BZX84C3V9W

I think I have found where these models are coming from https://www.diodes.com/assets/Spice-Models/Discrete-Prodcut-Groups/Zener-Diodes.txt I will submit a fix sometime later this week.

If that's the case then the copyright notice has been removed when importing these model into this library which is a copy right law violation I think. It says that these model may be coped for research and design and that they have to be copied intact including the copyright notice. So to avoid any possible legal issues I would suggest to copy that file completely into the repository.

@nexx512 That is why I ended up not submitting the fix. Having them all in one place would be very nice indeed but legality of such a compendium is questionable. I'm not a lawyer and can't consult one, so I have to avoid touching this. It would be nice of course if Diodes Incorporated and others released their models with some more permissive license.

@fedorkotov Good point. Unfortunately I already posted a pull request where I manually fixed some models, but only syntactically. They probably don't work for simulation. If i had read this issue before, I wouldn't have done that and stayed away from this repo.
