Subject: Guard Cells with PSATD: Fill With Inverse FFT, Damp Fields (#1867)

* Loop Over Full Box in Inverse FFTs

* Enable Fields Damping in Cartesian Geometry

* Minimize Style Changes

* Fields Damping: Fix Tileboxes For General Case

* Clean Up

* Assume Periodicity For Last Nodal Point in Inverse FFTs

* Update Benchmark of averaged_galilean_2d_psatd

* Update Benchmark of averaged_galilean_3d_psatd

* Update Benchmark of averaged_galilean_2d_psatd

* Update Benchmarks

* Update Benchmark of pml_psatd_dive_divb_cleaning

* Clean Up: Use More Descriptive Names
