[DEV] Ghostmark

Hi,

recently I saw this cartridge from Jed, inspired from BunnyMark to do a benchmark. So I decided to check what could be the results of the console without any optimization.

So basically I got different numbers of sprites before a downgrade of the FPS:

• ~ 7.000 sprites with Python
• ~ 16.000 sprites with Lua
• ~ 50.000 sprites with Rust

Python is really slow :) And all the drop of performance (for Python/Lua) are between the calls of functions from the scripting language to the engine, but the results are not so bad, specially considering that I have not really done any optimisations in many functions.
