Adding post-processing routines to compute surface forces

[bernardopacini]

Purpose

Previous post-processing used a routine to compute force on a geometry in a specific direction and only ran for one time step. This new routine computes the forces normalized by area over the specified patches, without specifying a specific direction. This is then written to a file that can be opened when visualizing the case. This can later be used to compute additional data. The utility runs on the time steps specified by the user, or runs all the time steps if the time option is not set by the user.

Type of change

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (non-backwards-compatible fix or feature)
• Code style update (formatting, renaming)
• Refactoring (no functional changes, no API changes)

Testing

I have tested this on some cases, but would appreciate more people testing it! I did not add any automated testing.

Checklist

• I have added new tests that prove my fix is effective or that my feature works
• I have added necessary documentation

This is a draft because I would like to fully replace the existing calcForcePerS utilities with these versions. @friedenhe let me know if you are okay with these new versions and if yes, I will update the PR to replace the old routines with these ones.

I went ahead and replaced the previous implementation with the new functionality. @friedenhe please let me know if this new version works for you, and if so, I'll convert this from draft. If you are able to test it for some cases too, that would be helpful.
