[REF] *: Introduce o-spreadsheet-engine package

This commit is the first step towards running the Spreadsheet Model
without the need of a web environment. It introduces the
o-spreadsheet-engine package (almost empty for now) to host the model
and all its dependencies (plugins, functions, ...).

It should not have any impact in the development workflow as the npm
commands have been updated to build/test/lint the new package as well.
