[Internals] Switch to TaylorDiff.jl for generator derivatives.

[lrnv]

This PR tries to switch from TaylorSeries.jl to TaylorDiff.jl because of better performances of the later.

But there is still a few broken tests.

See https://github.com/JuliaDiff/TaylorDiff.jl/issues/61 for upstream report of the bugs.

See also https://github.com/JuliaDiff/TaylorDiff.jl/issues/62, regarding the amount of additional dependencies, which would need to be merged before we go on here
