Optimised Abaqus interface

[tmnp19]

• Optimised the way the field outputs are written and treated inside piglot. Now piglot only writes the fields and the set names that are present in the YAML file and automatically extrapolates to nodes units that are calculated at the integration points;
• Added errors to check for non-linear fields in linear simulations;
• Fixed some bugs on the implementation of the selected instance on abaqus;
• Generalised the reading of Abaqus input fiiles.

Thanks for the effort, these are nice improvements. I've left some minor comments that should be quick to address. We should be able to merge this quickly.
