lp_colourclean v2.0

'lp_' is not really the name inside of Nuke, it's more for organizing on a server/computer harddrive

Update v2.0
(v1.0 was never released)
- removed Median as an operation (hella slow!)
- added C_Bilateral as an operation
- reworked the channel selection to only show the appropriate options
- removed legacy and rather useless functions left and right

ColourClean is a simple to use tool to clean different channels; it lets you choose different colourspaces and individually enable and disable channels to filter (note: you can't set individual values for individual channels). You can use a blur, defocus or bilateral operation to tackle issues inside the channels; I found that e.g. filtering only Cb and Cr channels with a bilateral operation is great for reducing compression artifacts tremendously.
It accepts a mask and also lets you premult this area before filtering it, this prevents bleeding from other parts of the image. This is a pretty neat function, regardless of beeing so simple :)

ColourClean was the first tool I built for myself, and it showed; I haven't used it for years. With the re-vamp of v2.0 this will change now.

This tool is a Group, not a Gizmo; edit if needed.
