Release of version 0.7

[fwitte]

A new version of TESPy had been in the making since about 9 months, finally uploaded it to PyPI! You can test it by upgrading your installation with pip install tespy --upgrade. Note, that support for python versions lower than 3.9 is dropped! See what is new in the docs: https://tespy.readthedocs.io/en/main/whats_new.html.

Let me know, if there is any bugs or things not working as intended anymore!

Thanks :)
