Feature Request: BC6H Signed Float Support (DXGI_FORMAT_BC6H_SF16)

[peeweek]

It would be really interesting have support of signed half data (eg: to compress SDF, Vectorfields (both 2D or 3D in BC6H, which is a huge memory saver, especially in Texture3D)

Seconding this, BC6HS support would be super useful.
