v0.2.0

Merge branch 'main' of github.com:zooks97/aiida-openmx into main

v0.1.0a0

This release has the absolute minimal functionality for running a basic SCF calculation using OpenMX.
In its current state, it will not work without an unreleased version of aiida-pseudo!

It includes:

• A barebones OpenmxCalculation CalcJob implementation
• Input validation via a limited JSON schema
• No output parser
