Add "Blend" node (#1024)

Browse Source 
* Add Blend node

* Add more implementations

Currently, known buggy implementations:
* Color Burn
* Saturation

Opacity is currently achieved by linear interpolation, this will be changed as soon as all filters are implemented.

* Add more implementations

Currently, known incorrect implementations:
* Color Burn
* Saturation

Not yet Tested:
* Linear Burn
* Linear Dodge
* Vivid Light
* Linear Light
* Pin Light
* Hard Mix
* Subtract
* Divide

Opacity is currently achieved by linear interpolation, this will be changed as soon as all filters are implemented.

* Cleanup

* Removed Unused Code
* Fixed Clamping Issue
* Fixed Inverted Opacity
* Moved Opacity Calculation from individual  Blend Functions into 'blend_node' function

* Fix 'Color Burn' blend mode

Currently, known incorrect implementations:
* Saturation

Not yet Tested:
* Linear Burn
* Darker Color
* Linear Dodge
* Lighter Color
* Vivid Light
* Linear Light
* Pin Light
* Hard Mix
* Subtract
* Divide

Opacity is currently achieved by linear interpolation, this will be changed as soon as all filters are implemented.

* Fix 'Saturation' blend mode

Currently, known incorrect implementations:
* None :D

Not yet Tested:
* Linear Burn
* Darker Color
* Linear Dodge
* Lighter Color
* Vivid Light
* Linear Light
* Pin Light
* Hard Mix
* Subtract
* Divide

Opacity is currently achieved by linear interpolation, this will be changed as soon as all filters are implemented.

* Final Cleanups

* Add proper Inputs

* cargo fmt

* Add test for doubling number

* Display implementation for ProtoNetwork

* Switch top and bottom

* Add input types for blend image node

* Fix test
