SpatialUnderstanding truncates pointers in x64

[jwittner]

I get these warnings which scare me when building for x64:

1>PlaySpace\PlaySpaceInfos_W.cpp(3682): warning C4311: 'type cast': pointer truncation from 'U8 *' to 'U32'
1>PlaySpace\PlaySpaceInfos_W.cpp(3682): warning C4302: 'type cast': truncation from 'U8 *' to 'U32'

@jevertt Seem dangerous to you?

[jevertt]

It's not ideal - this was developed targeting a specific platform. Would be nice to find a cleaner way to do this.

[jwittner]

Perhaps we can drop the other platforms from the solution so that it's clear what platforms SpatialUnderstanding supports?

[jevertt]

Sure - that sounds reasonable.
