Python: Start 1D Support (#2582)

* Python: Start 1D Support

Start supporting 1D builds in Python.

* Fix 1D: PML FillZero unused

... since PMLs are not yet supported in 1D.

* BeamRelevant: Fix unused p_pos0

* FromTXYEFileLaserProfile: Not Impl in 1D

* QED Schwinger: 1D not Implemented

Fix unused warnings, add aborts.

* 1D RealVect/IntVect: Initialization

Use explicit scalar constructors, no braces.
Fix warning in clang 10.

* 1D NCI Filter: Fix unused members & Init

Unimplemented, but throws warnings.

* PSATD: 1D not Implemented

- remove compile warnings
- start porting some parts

* NCIGodfreyFilter: Clean up 2D & Else
