add single `state` field to Lie operators and Taylor maps

[mattsignorelli]

This will contain all information about the map, e.g. idpt, FD, etc.

[mattsignorelli]

One thing to add to state may be whether or not the map is in phasor's basis where the poisson bracket definition is different

[mattsignorelli]

actually, because one will almost always have separate maps for each particular , it makes sense to instead put as much information into the type itself as possible. Therefore I will instead remove idpt and put it int the type alone, and mybe add a new field in_phasors::Bool
