Review SamplingModel from old Kairos and add it to the new timeline items model

[natan-sinigaglia]

all the keyframes that sample upstream needs to have a Sampling model that describe what kind of transportation function to apply to the domain.

Check use case scenarios in other software like ableton

Keyframes now have a fix IDomain1DTransportFunction implementation.

next step is

• Move all the mapping stuff to AlchemX and generalize it like we did for interpolation and blending
• have Dynamic instantiation of IDomain1DTransportFunction implementations (advanced controls) in LayerX 1D cathegory
• Basic implementation of these is InBoundOffset (To sample the layer from the beginning of the keyframe)
• There could be an enum to define if the time that we pass inside is Absolute or Relative (relative would be the default and it would subtract the keyframe position)
• define the signature of IDomain1DTransportFunction . Do we always provide the In Bound and Out Bound?
