Equirectangular renders and the denoiser

Currently the denoiser creates visible edge seams on equirectangular cycles renders.

Presumably this happens because the denoiser operates on the edges of the rendered image without knowledge of the tiled elements it will be next to when later used as an HDRI environment.

Something that automatically tiles a small number of pixel rows/columns around the image before passing it to the denoiser, and then crops the original image back out of the output automatically, would be an amazing feature.
