Unable to acces new Qt features

# The wrapper is very outdated

From the beginning, my biggest affair about switching from using Qt with the official C++/Python to a wrapper was the fact that we **would rely on** a repository maintained by just one person plus a few more contributors.

I've noticed that *therecipe* is still relying on the unsupported **Qt 5.13**, which was released a year and half ago, while **Qt 5.14** was released a year ago, **Qt 5.15** half year ago, and the next major version, **Qt 6.0**, at our doors, coming in a few days. What is more, *therecipe* ***has not included any new feature since Qt 5.13***.

And after made a quick `git log`, I realized that, indeed, **no relevant changes to the repository has been done in the last year and half**.

## **Any good notice?**

Yes. Many bugfixes will be still available just by running `qtsetup` over the latest version of **Qt 5**.

## But...

**All Qt 6 new features, bugfixes and performance improvements will not be available at all since is not source-compatible with Qt 5, so it's no possible to run `qtsetup` against Qt 6.**

## So... what's the solution?

Be patients. This is a blocker for many issues.
