Release PyAT 0.6 · atcollab/at

Main changes

First release under the Apache 2.0 license
Support of python 3.12
Introduction of a beam slice monitor for simulation of collective effects
Introduction of new "Variable" objects (still preliminary)
Lattices may be loaded and saved in JSON format. AT files in JSON format can be used for exchanging lattices between Matlab and python, as an alternative to the proprietary .mat format.
