Fix panic on 64 bit machines with go 1.1

I see the following panic when I try to read files with the current
version of go:

    panic: buffer.check_count: object of class [TNamed] read too few bytes (4 missing. expected 28, got 24)

I've fixed it by specifying that the values being read are `uint32`
rather than `uint` (which is variable size depending on the platform
we happen to be reading from).
