Add a safe preset

[DeMoorJasper]

It would be nice to have an option called safe that sets the optimal preset for minifying html safely, without having to thinker around untill you get a universal htmlnano config that works safe for everyone.

This idea came from trying to optimise the universal config for parcel, as we from time to time get a bug report with an unsafe transform.

If there is intrest for this feature but no available time, I'd love to implement this

Hi @DeMoorJasper,

I'm definitely interested in making htmlnano minifications safe by default for all types of HTML. Actually, I think we don't need a preset for that. All modules should minify code without breaking it by default. That was also my intention initially. And if someone wants to minify their code even more they could enable some hard-minifying options (in such case a preset you suggested would come in handy).

So I think we should solve that issue by changing the default modules config. Your help would be really appreciated, as, unfortunately, I don't have time right now for that. How does that sound to you?

Awesome! I'll do a PR in a bit

@DeMoorJasper thanks for making the default minification options even safer! I published new version 0.1.9.
