SVT-AV1-PSY features coming to SVT-AV1

I'm proud to announce that 8 SVT-AV1-PSY features will be making it into the next mainline SVT-AV1 release!

The 8 features are:

• Variance boost curve selection (adopted from our "enable alt curve")
• Sub-64px dimension support
• TF strength + adaptive TF
• Color help for help with printing encoder colorspace information
• Odd resolution support
• Luminance QP Bias (adopted from luma bias)
• Adaptive film grain
• User-configurable sharpness through --sharpness

We are beyond excited to have mainline behind our perceptual methodology & the features we've authored to support it, and I expect even bigger feature integrations stemming from deeper collaboration in the future. The mainline team have been amazing to work with – looking forward to more in the future!
