Compiler error on Visual Studio 2019

Repro steps:
1. Get OpenVDB using vcpkg (command line I was using: "vcpkg install openvdb:x64-windows"
2. Run "vcpkg integrate install" to get vcpkg to includes/libs to be automatically picked up by Visual Studio
2. Compile anything with "#include " in VS 2019

The error I get is
"error C4146: unary minus operator applied to unsigned type, result still unsigned" coming from NodeMasks.h lines 112 and 134, code below:

return DeBruijn[Index32((v & -v) * 0x077CB531U) >> 27];

Easy fix would probably be to just cast it to an int and then cast it back to a uint after all is said and done

Start with NodeMasks.h at the reported lines 112 and 134, then reproduce the issue by installing OpenVDB with vcpkg and compiling a file that includes openvdb/openvdb.h in Visual Studio 2019. Done means the reported C4146 error no longer occurs during compilation.
