Ran out of memory on examples

[Hluppppppppppppppa]

Hi!
I tried to run examples using PCSX-Redux emulator.
But when I try to run "Monkey" and "Donut" examples, they are immediately falls into panic. Even in the case when I maximize system RAM to 8MB in emulator settings.

Monkey error:

Panicked at /home/hlupa/Sources/psx-sdk-rs/psx/src/lib.rs:128:5
Ran out of memory Layout { size: 7000, align: 2 (1 << 1) }

Donut error:

Panicked at /home/hlupa/Sources/psx-sdk-rs/psx/src/lib.rs:128:5
Ran out of memory Layout { size: 4608, align: 2 (1 << 1) }

Am I doing something wrong? I don't think examples should fall into error like that.

Hello! The examples define a small fixed-size heap like this. Have you tried increasing it as explained in the docs?

@Hluppppppppppppppa I ran into this problem some time ago on an old PR (#31 (comment)) ... I can't remember what I did to fix the problem back then, but trying again now, because I get exactly the same messages and sizes as you report (edit: even though we are using different emulators, i just noticed, I'm using Mednafen) :

psx-sdk-rs/examples/monkey/src/main.rs

Line 14 in 06d7913

psx::sys_heap!(4 kb);

 psx::sys_heap!(8 KB);

Keeps the value a multiple of 4 as documented, and is greater than the what seems to be required 7000 bytes..

Similarly for the donut example, increase it from 4 to 8KB

psx-sdk-rs/examples/donut/src/main.rs

Line 13 in 06d7913

psx::sys_heap!(4 kb);

 psx::sys_heap!(8 KB);

I don't really understand why there is a difference -- it sounds like maybe different BIOS's behave differently?

I think increasing the size of both examples to 8 KB would make the examples more flexible and not break anything for systems where 4 KB worked?

I'll happily raise a PR for this if there is no downside.
