Release v2.2.0

Modeling polarized X-ray signals has been implemented and examples added for simulating polarized pulses (Stokes parameters) using a couple of different atmosphere options. Support for polarized likelihood calculation has also been included. In addition, new integrators (with and without polarimetry) have been implemented to allow atmosphere interpolations with 5 parameters to be performed in 2 steps. See further details reported in https://github.com/xpsi-group/xpsi/blob/main/CHANGELOG.rst.

Release v2.1.0

Atmosphere switching implemented without need for re-installing X-PSI for different atmosphere extensions. Note the required changes in the installation procedure and python scripts reported in https://github.com/xpsi-group/xpsi/blob/main/CHANGELOG.rst.
