Import report items as json

[dcansys]

This is implementation of reading, converting and inserting report items through the JSON format.
Items JSON import will load a JSON file, create a default template, and save all report items to ADR.
JSON Schema is in the documentation.

PoC: https://github.com/ansys-internal/adr_mechanical/tree/poc/import-report-items-as-json

Note: more enhanced default template with basic ToC and sections will come in the next iterations.
