Cannot assign to slice of `byte` or `short` (or unsigned counterparts)

[jblachly]

Example code provided by mir:

/+dub.sdl:
dependency "mir-algorithm" version=">=2.0.0"
+/

void main()
{
    import mir.ndslice;

    auto matrix = slice!double(3, 4);
    matrix[] = 0;
    matrix.diagonal[] = 1;

    auto row = matrix[2];
    row[3] = 6;
    assert(matrix[2, 3] == 6); // D & C index order
    
    import std.stdio;
    matrix.writeln; // [[1, 0, 0, 0], [0, 1, 0, 0], [0, 0, 1, 6]]

This code works fine for all numeric types except (u)byte and (u)short. I saw #100 and kind of understand why byte fails, but why does (u)short also fail? (Error: matrix[] is not an lvalue and cannot be modified) Presumably it is because the internal representation. Explicit short(<num>) works in this case just as with byte.

If this is a won't fix, I would politely request a note in the documentation that byte and short should in general not be used. This bit me tonight while working with 16-bit image data and I was storing as short ndslice.

Thanks again for this amazing library.

Fixed in v3.10.88
