Owen Harvey ec80876ed1 Adding checks when looking for loops to handle NaNs.

Updating some OpenSCAD functions that have the potential to return NaN
or (+-)Infinity have been given checks that remove these troublesome
values and clamp them to "reasonable" values so that the rest of the
processing can continue without processing these troublesome values.

Version next (202Y-MM-DD)

ExtOpenScad interface changes
- Added rands and lookup support #433
- Added several primitives
  - cone(r, h, center)
  - torus(r1, r2)
  - ellipsoid(a, b, c)
- Adding vector-matrix, matrix-vector, and matrix-matrix multiplication support to * #414
- Several mathematical functions that have undefined values for some inputs or tend to infinity have been given finite but extremely large bounds.
Haskell interface changes
- Added matching primitives for cone, torus, and ellipsoid
- Adding vector-matrix, matrix-vector, and matrix-matrix multiplication support to mult #414
Other changes
- Migrating StateC and StateE to a ReaderT/WriterT/StateT transformer stack, rather than being just StateT. #432
- Fixing an off by one error in variable stack lookups. #431
- Fixing exponent operator precedence. #428
- Fixing some crashes relating to unclosed loops when generating surfaces. #373

Version 0.4.0.0 (2022-06-06)

Changelog started. Previous release was 0.3.0.1.
Haskell interface changes
- Added support for XY-scaling on linear_extrude #269
