Deasy - quick HBD denoiser

[anton_foy]

Yet another denoising filter DEASY

Usage (first for Luma filtering and then Chroma filtering):
Deasy_L()
Deasy_C()

or with a more robust chroma denoise, Deasy_CM:

Deasy_L()
Deasy_CM()

or combined luma and chroma, Deasy_LC:
Deasy_LC()


### Needs: avs+, hqdn3d, rgtools, extools, sharpenerspack(dogway), masktools2, fft3dfilter, neo_f3kdb and manyplus

## Deasy_L ##

It's right in line??
\hqdn3d(lt=tcow, restart=restart))

[anton_foy]

It's right in line??
\hqdn3d(lt=tcow, restart=restart))

Thanks, I think its okay now...beers made me (don't) do it.
