[riderx]

This PR add support for Unocss.

Related to #21

I'm not certain how to test what I have done.

So, I made the logic without testing.

If @antfu you are willing to have a check, specially for the transformation rule function, i'm not sure i understood it well

Sorry UnoCSS does not support Tailwind plugins, this probably won't work.

@antfu thank you so much for the answer.
If you look in konsta code I modified, it doesn't use much tailwind code, since it's made originally to be around a tailwind config file.
Like that :

const konstaConfig = require('konsta/config');

// wrap your config with konstaConfig
module.exports = konstaConfig({
  // rest of your usual Tailwind CSS config here
  ...
});

To what I have see there are hope!

My questions were more about how to rewrite the tailwind rule to make them work in UNOCSS.
Konsta is the only nice alternative to ionic for mobile app design, it could be a nice addition to unopreset.

@antfu I think I'm not far from having made a Tailwind to Unocss preset function.
Maybe that could be a project on his own.

Unocss is above Tailwind for me, but it lacks of all the plugins made for Tailwind, so with something with that I believe more and more people would switch.

I will continue to see if I can reach a viable point.

@riderx Have you make it work? I would also prefer using it with Unocss
