Release of RTK v2.2.0

Dear RTK users,
RTK v2.2.0 <https://github.com/SimonRit/RTK/archive/v2.2.0.zip> has just been
released, about fourteen months after RTK v2.1.0. This release is intended to
produce python packages compatible with ITK v5.1.1 and v5.1.2 (current release
on pypi.org). I will soon prepare another release for ITK v5.2.

Release notes:
* New projectors with PSF correction for SPECT reconstruction
* New quadratic regularization in OSEM
* Progress reporters for FDK and iterative reconstruction algorithms
* New continuous integration using Github actions, following ITKModuleTemplate
* Alignment with ITK developments
* Enhanced Python wrappings
* Many compilation, bug and style fixes

Many thanks to all contributors for this release, in alphabetical order:
Sebastien Brousmiche, Aurélien Coussat, Julien Finet, Lucas Gandel, Hans
Johnson, Matt McCormick, Antoine Robert, MrTzschr, Simon Rit, Pierre-Antoine
Rodesch and Vincent Libertiaux.

As usual, be aware that we do not focus on releases since we have a public
github repository <http://github.com/SimonRit/RTK> that we aim at keeping
stable. I still recommend the use of the master HEAD over releases to enjoy the
new RTK developments before their release. Corresponding python packages can
now be downloaded from the Github action. We still have a few on-going
projects for which we will use and enhance RTK.
