ISO Loader 0.6.x Beta

For full loaders with cso you should use 0x8c000100 or high memory.

Is there a place where the reasoning behind memory address selection is explained ?
For example, is it generally better for the loader to start at a lower address, while it's generally better for the software being run that the loader be placed at a rather higher address ?

This part is nebulous to me, the ISO loader proposes a lot of addresses, but without explanation, I tend to blindly follows config lists like the dragoncity one,
yet I see other people/video suggesting different address, and after testing, many of them work, so it's really not satisfying to understand why select one rather than the other.

@swat post states that one parameter for this choice is the binary size of the loader, suggesting that the "right" address depends on the loader and its version. Maybe on other parameters? or even the image being loaded too.

As a data point, `sd_cso.bin` is 30.5 KB,
compared to previous betas of `sd.bin` :
v0.6.11 => 28.6 KB
v0.6.10 => 27.6 KB
v0.6.9 => 27.3 KB
v0.6.8 => 26.9 KB
So it seems to be slowly growing overtime (even without cso support).
And presumably, it could have an impact on address selection.
