Added branch support/aiida-1.X from version 0.13.0

[Irratzo]

Hi! I added the branch support/aiida-1.X. It is is based on release 0.13.0. It should remain fixed at that version and not be updated.

This branch is aimed at those who need a Python environment with aiida-core[atomic-tools] 1.x (1.6.9 = last before 2.0) and masci-tools[cmdline-extras] installed.

masci-tools[cmdline-extras] 0.14.0 added the requirement 'pymatgen-io-fleur~=0.4,>=0.4.1'. This, in turn, requires pymatgen==2022.7.8, resp. pymatgen>=2022.7.8. While aiida-core[atomic-tools] 1.6.9 has the constraint pymatgen!=2019.9.7, <=2022.02.03 and >=2019.7.2.

This dependency conflict can be fixed by downgrading to masci-tools[atomic-tools] 0.13.0, respectively this branch pinned at 0.13.0.

(Here is a non-public reference for an AiiDA JupyterHub installation where this issue occurred. Here, the installation of aiida-core[atomic-tools] 1.6.9 and masci-tools[cmdline-extras] 0.13.0 succeeded. Here, the installation of aiida-core[atomic-tools] 1.6.9 and masci-tools[cmdline-extras] 0.14.0 failed due to the dependency conflict described above.)
