Add a "view mode" for IDEs where one can pick a style of Fortran code

Suggested here: https://fortran-lang.discourse.group/t/should-i-indent-the-codes-below-contains/2164/7

What I am waiting for (or planning to look into options for) is a “View” mode in IDEs where one can define/pick a style and Fortran code can then simply be viewed in that style regardless of how it is in the actual source content.
