FFT improvements (#81) 
* Use built-in `reverse_bits`; remove duplicate `reverse_index_bits`.

* Reduce precomputation time/space complexity from quadratic to linear.

* Several working cache-friendly FFTs.

* Fix to allow FFT of constant polynomial.

* Simplify FFT strategy choice.

* Add PrimeField and CHARACTERISTIC properties to Fields.

* Add faster method for inverse of 2^m.

* Pre-compute some of the roots; tidy up loop iteration.

* Precomputation for both FFT variants.

* Refactor precomputation; add optional parameters; rename some things.

* Unrolled version with zero tail.

* Iterative version of Unrolled precomputation.

* Test zero tail algo.

* Restore default degree.

* Address comments from @dlubarov and @wborgeaud.

Delete coset [I]FFT methods (#72) 
I think they had a mistake, and in any case we have a similar method in `polynomial.rs` now which has tests.
