Actually i have an implementation i did back in 2017, probably 
needs more testing, but would allow ANY size (multiple of 32/64 
bit), works compile-time and real time, and division has it's own 
asm code to try and speed it up.

I need to double check to make sure it still works in today's D 
compilers, but otherwise it may be a quick and easy drop in.
