Special cases for extension field arithmetic (#138)
We previously checked for special cases, like arithmetic on constant Targets, in `arithmetic`. We can handle those cases without actually adding an `ArithmeticGate`.

Now that `arithmetic` just calls `arithmetic_extension`, it makes more sense to check for special cases in the latter method, so it applies to both base and extension field arithmetic.

Reduces gate count from 16149 to 15689.

Move stuff around (#135)
No functional changes here. The biggest change was moving certain files into new directories like `plonk` and `iop` (for things like `Challenger` that could be used in STARKs or other IOPs). I also split a few files, renames, etc, but again nothing functional, so I don't think a careful review is necessary (just a sanity check).

Division related changes (#99)
* Division related changes

- Simplify `div_unsafe_extension` using virtual targets
- Add methods for inversion and safe division

As a followup I'll switch some calls to safe division.

* Test safe division also

* add_virtual_extension_target

Benchmark tweaks (#83)
- Configure FRI with a list of arities that's more appropriate for a 2^14 instance. The previous config resulted in a huge final polynomial.
- Log the blinding factors, and other logging tweaks.
