PySide6 support

[WhyNotHugo]

Trying to use this fails with:

During handling of the above exception, another exception occurred:

The latest release of PySide is packaged as PySide6, so this fails. Any change of adding support for it?

you mean Pyside2-6 ? you may rather use "pyside2", and nevertheless, Spyder team doesn't expect to support Pyside2-5 before Spyder-5... somewhere in 2021. In the mean time, you'll have the more basic Pyzo that may work.

@WhyNotHugo, this depends on support for PySide6 in QtPy. Fortunately, someone is already giving us a hand with that in spyder-ide/qtpy#225, so I expect to release a new version in two or three weeks.

[WhyNotHugo]

@stonebig Pyzo seems to be something entirely different to qtawesome.

@ccordoba12 Interesting! I wasn't aware that qtpy was also a spyder project! You guys are doing lots of great stuff!

I'll follow that PR to keep in the loop, thanks!

Closing in favour of https://github.com/spyder-ide/qtpy/pull/225/.

Thanks for your kind words!

And thanks for your patience too.
