Add correction factors for pressure-based Green function

[RShaw026]

Description and Context

In PR #87, The pressure-based Green function was added. In this PR, the correction factors corresponding to the pressure-based Green function are added. These values are calculated by using MIRCO to solve a contact between a linear elastic half-plane and a rigid flat-indenter.

@isteinbrecher @mayrmt FYI Since MIRCO currently consumes a lot of memory and time to solve high-resolution problems with large contact area percentages (in this case: flat indenters), our MATLAB-based bem-code is used to calculate these factors.

[RShaw026]

@RShaw026 These factors are constant, so you could make them constant in code as well.

Am I right, that each vector entry corresponds to a certain resolution? Where is it documented, which resolutions these vectors cover?

Yes, you are right. It is not mentioned here, but currently, MIRCO works only from the resolution of 1 to 8. (2^n+1 times 2^n+1 nodes grid)
