[WIP] Add 1d cylinder and sphere

[dpgrote]

This large PR adds 1d cylindrical and spherical geometries.

This touches many files, every place that has a dependency on the dimensionality. One complication in these geometries is that there is no z-axis, so some parts of the code (the moving window, boosted frame, and BTD diagnostics) are not applicable, and require changes there to avoid compilation problems.

Current status:

• cylindrical works, producing correct results in Langmuir test
• spherical works, producing correct results in Langmuir test
