CapacityError in grain.rs

[sonic41592]

Hello, I get a CapacityError when trying to run this on a video I encoded with SVT-AV1. This will be an amazing tool if I can get it working properly, I've been very disappointed that SVT-AV1 doesn't have external denoising, and this will work perfectly to achieve the same thing.

After some testing, this error seems to be caused by 10bit color depth video, since an identically encoded 8bit video works just fine

[sonic41592]

I did some more testing, and I believe SVT-AV1 temporal filtering is causing the error. Encoding with the option 'enable-tf=0' solves the error. With temporal filtering enabled, using grav1synth inspect works for the first couple thousand frames before erroring. I think the film_grain_params is being given an improperly parsed BitInput for those frames, causing junk data until num_y_points exceeds it's maximum value of 14, causing the error. Interestingly, using presets 6-13 work just fine as well.
