Issue Description:

Working with raw buffers is extremely unsafe because all typed loads/store assume alignment, but there's no way to check for and adjust alignment short of retrieving the baseAddress' bitPattern.

Some folks have insisted that specifying the alignment at buffer allocation time mitigates some of the unsafety. I completely disagree. Alignment needs to be ensured at the point that the buffer is used, not when it is allocated.

We should have an API that allows the user to ask for a raw slice of the raw buffer while rounding up to the nearest alignment for T. This API could return a new type, say

RawMemorySlice<T>

which can be used to reinterpret the aligned raw buffer slice as T without binding/rebinding the buffer's memory.
