Sean Cross	5dfad296ae	xous: mark MemoryRange::as_slice and friends as unsafe ... Mark `MemoryRange::as_slice()` and `MemoryRange::as_slice_mut()` as unsafe. This is due to the fact that not all representable types can be cast to an arbitrary value. For example, if Process A sends random values to Process B, then Process B casts the memory to a slice of `bool`, then any values that are not 0 or 1 are undefined. Because these functions can leak UB into the program, they are marked as unsafe. This patch adds `unsafe {}` blocks to all instances where this function is called. Additionally, all instances have been checked to verify that they do not cast to any invalid types -- most use `u8` or `u32`. Additionally, the long-deprecated `MemoryRange::from_parts()` call was removed, since that causes UB without being marked as unsafe.
