[FEATURE] Add support for the dvh, lvh and svh length units

[KaiOnGitHub]

Fixes #412

[oliverklee]

Hi @KaiOnGitHub, thanks for this PR!

Would you be willing to cover it with a unit test?

[KaiOnGitHub]

@oliverklee I fixed the char limit but unfortunately don't have the time to write a test atm. I tested it within our Shopware 6 application and with this change dvh worked while it did not before :)

[JakeQZ]

@KaiOnGitHub, thanks for providing the code changes and testing it within your app. If you still don't have time to add the unit tests, I may be able to pick this up - please don't delete your branch!

@oliverklee, I tried to rebase this branch, but couldn't figure out what I was supposed to do. This time, I will simply re-apply the changes as a separate PR. But for future reference, what was I doing wrong here?:

- Checking if the <src> being pushed ('HEAD')
  is a ref in "refs/{heads,tags}/". If so we add a corresponding
  refs/{heads,tags}/ prefix on the remote side.

Neither worked, so we gave up. You must fully qualify the ref.

Step 1: From your project repository, check out a new branch and test the changes.

git checkout -b KaiOnGitHub-patch-1 main
git pull https://github.com/KaiOnGitHub/PHP-CSS-Parser.git patch-1

Step 2: Merge the changes and update on GitHub.

git checkout main
git merge --no-ff KaiOnGitHub-patch-1
git push origin main

Trying this now.

I can see this is totally stupid. It will clearly merge the changes into main without review. Fortunately I already know that the suggestions from git and GitHub are usually utter rubbish, so have not done this.

Much simpler to just start over. Avoids a waste of time with systems that don't work or cannot be understood.

@JakeQZ Maybe the GitHub documentation for working on a PR branch of a fork is helpful: https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/committing-changes-to-a-pull-request-branch-created-from-a-fork

(I have to admit that I have never tries this myself.)

@JakeQZ Maybe the GitHub documentation for working on a PR branch of a fork is helpful

Yes, if the PR submitter has enabled “allow contributions from maintainers” setting, you’ll be able to commit to their forked branch.

However, I find that, for simple merge conflicts, the web-based UI GitHub provides is usually sufficient (I used it in this case).

I think I maybe went wrong by fetching the remote PR into my local repo. Didn't have a problem after cloning their fork into a separate directory.
