̶r̶l̶e̶ ̶ Delta triggers undefined behavior

[a10y]

Describe the bug

I'm running some tests using a small sample of the new Github Archive dataset and hitting undefined behavior check failures in RLE due to out of bounds indexing in the decode step:

warning: `bench-vortex` (lib) generated 1 warning (run `cargo fix --lib -p bench-vortex` to apply 1 suggestion)

unsafe precondition(s) violated: slice::get_unchecked requires that the index is within the slice

This indicates a bug in the program. This Undefined Behavior check is optional, and cannot be relied on for safety.

[0ax1]

The issue is seemingly in Delta, not RLE. Decompressing RLE on encode, before indices get Delta encoded, when writing the file, does not result in invalid indices.

     pub fn encode(array: &PrimitiveArray) -> VortexResult<Self> {
-        match_each_native_ptype!(array.ptype(), |T| { rle_encode_typed::<T>(array) })
+        match_each_native_ptype!(array.ptype(), |T| {
+            let rle_array = rle_encode_typed::<T>(array);
+            let _slice = array.as_slice::<T>();
+            std::hint::black_box(rle_decompress(&rle_array.as_ref().unwrap()));
+            rle_array
+        })

If the issue would be in RLE, the decompression should fail here. Before cascading compression indices and values are primitive arrays.

Delta compression/decompression being broken can be reproduced with:

The assumption is that nullability is not handled correctly.
