MIDI Mapping broken when adding effect

[hepi.yellow]

The scenario:
- I have a clip with a Transform effect.
- I map the Position Y value to a MIDI.
- I add another Transform effect BEFORE the existing one.
- The previous MIDI mapping is broken now, since it no longer controls the Position Y of the initial Transform effect. It controls the new Transform effect.

(This is applicable for any effect not just transform)

Analysis
MIDI mapping of effect parameters are bounded by the effect-name & the index of the effect in case of multiple effects with the same name.

Solution
Add a flag for:
Binding: [Effect-name & Index] or [Effect Instance]

When [Effect Instance] is chosen, then the MIDI mapping would stay as it is, regardless of any other effects which are added.\

(This is mostly relevant when the binding is "This Clip/Layer/Group")
