Is there a way to create a 24-bit int? One that for all

int24[] that work properly, etc.
I haven't looked at endianness beyond it working on my
computer. If you have special needs in that regard, consider
this a starting point:
struct int24 {
ubyte[3] _payload;
this(int x) {
value = x;
}
...
}

You may also want to put an align(1) on it so that you dont
waste 25% of the allocated memory in an array of int24's
The whole point is so that there is no wasted space, so if it
requires that then it's not a waste of space but a bug.
Audio that is in24 is 3 bytes per sample, not 4. Every 3 bytes
are a sample, not every 3 out of 4.
Basically a byte[] cast to a int24 array should be 1/3 the size
and every 3 bytes are the same as an int24.
Thanks for pointing this out if it is necessary.
