fix(postcss-colormin): Strict color parsing

[omgovich]

Fixes #1120
Fixes #1115
Fixes #1113

Colord v2 conforms to CSS Color Level Specs and ignores invalid <color> values, so upgrading will fix all of the issues we got last few days.

See omgovich/colord#53 for more details.

Let's add tests to ensure we don't break it again 👍

[omgovich]

How do you work with the integration tests BTW? They are HUGE and it seems impossible to check them.
They are falling (probably because they were updated during the migration to color v1.7) but I can't even see where is the error.

Agree, we need improve them, right now you can use smart diff locally and found which characters was changed (and maybe found regression)

[omgovich]

Ooof. Your integrations tests are killing me 🙃

1. What is smart diff? Can't google the thing)
2. How to update integration snapshots properly?

Help would be really appreciated since I'm a rookie in the repo.

Snapshots are fixed (tons of z-index: #999 were fixed there).
New tests were also added.

So we should be ready to go!

/cc @ludofischer can you look too? I think we need do release after merge

[ludofischer]

Seems straightforward enough to me. Let's try and release this!

[ludofischer]

Thanks a lot @omgovich for your hard work!

[michaelfaith]
