Physical constants updated in SciPy

[lfarv]

scipy 1.15 has been released on January 3rd. It updates the physical constants to CODATA 2022, instead of CODATA 2018 used previously. As a consequence, the Matlab tests run on Github fail until the Matlab constants are updated.

Until this is done, ignore the following errors in Matlab tests:

• pytests/ringparameters(lat2=hmba)
• pytests/ringparameters(lat2=spear3)

This is due to a different relativistic gamma because of the updated electron mass.

The constants in C are already set to CODATA 2022 (in #742)

The problem is slightly worse than anticipated: ScyPy 1.15 requires python >= 3.10. So python 3.7, 3.8 and 3.9 are stuck with the old constants.

Consequently, AT results are slightly different depending on python version…

The Matlab values are updated in #884. With this, the values in python>=3.10, Matlab and hard-coded in C are now identical.

The values in python<3.10 are still from CODATA 2018. AT results in these versions are slightly different form those of Matlab or python recent versions.

Partially solved in #884. But for python<3.10, we are stuck with old values
