Bug Fix: Resolved a type mismatch error

[bdorney]

Description

Changed mapVFATPos2VFATSN from int32 to uint32 data type. This resolves a type mismatch in older versions of numpy and is also more correct. The vfatID is treated as an unsigned 32 bit integer due to the possibility of bit flips in the chipID register.

I think I'm just gonna make VFAT serial number a float until reed muller comes along.
