Unsafe zero-copy slice casts for Go

Convenience functions for casting raw bytes to typed arrays without copying.

Usage:

b := []byte{1, 2, 3, 4}
v := unsafeslice.Uint32SliceFromByteSlice(b)

func StructSliceFromByteSlice

func StructSliceFromByteSlice(b []byte, out interface{})

Create a slice of structs from a slice of bytes.

var v []Struct
StructSliceFromByteSlice(bytes, &v)

Elements in the byte array must be padded correctly. See unsafe.AlignOf, et al.
