Fails to load planar DDS format textures #9

In DirectX 12, each plane of a planar format is it's own subsurface--in DX 11 all the planes were in the same subsurface. This means the current implementation of DDSTexutreLoader fails for:

DXGI_FORMAT_NV12 4:2:0 8-bit
DXGI_FORMAT_P010 4:2:0 10-bit
DXGI_FORMAT_P016 4:2:0 16-bit
DXGI_FORMAT_420_OPAQUE 4:2:0 8-bit
DXGI_FORMAT_NV11 4:1:1 8-bit

It would also fail for the JPEG Hardware decode formats added in DXGI 1.4

DXGI_FORMAT_P208 4:2:2 8-bit
DXGI_FORMAT_V208 4:4:0 8-bit
DXGI_FORMAT_V408 4:4:4 8-bit

Subresource indexing changed for planar types:

inline UINT D3D11CalcSubresource( UINT MipSlice, UINT ArraySlice, UINT MipLevels )
{
    return MipSlice + (ArraySlice * MipLevels); 
}

is now:

inline UINT D3D12CalcSubresource( UINT MipSlice, UINT ArraySlice, UINT PlaneSlice, UINT MipLevels, UINT ArraySize )
{ 
    return MipSlice + (ArraySlice * MipLevels) + (PlaneSlice * MipLevels * ArraySize); 
}

Updated to support load of planar formats
