Lots of changes (expand to read more)

- Update NOTES with new findings
- Add Cutter link to README
- Add ASMJIT, ASMTK and Zydis to CMake
- Make DX8 setting cofigurable via ScrapHacks REPL
- Add scaffolding for build hook trampolines using asmjit
- Add on the fly assembling of code to REPL
- Clean up command structure
- Add memory RWX to REPL
- Add stack dumping to REPL
- Add Gamevar dumping to REPL
- Add hook check to overlay commands (don't work if DX8 not hooked)
- Allow nested command definitions for cleaner REPL
- AllocConsole() as early as possible
- shuffle some code around for cleanup
- Add GameVar, PakEntry and HashIndex structures

## Features
- read and write memory
- change DirectX state
- Draw DirectX overlay (still need to make a useful overlay)
- Dump various data structures to the console
- Assemble and execute code on the fly
- Can be controlled via keyboard shortcuts (TODO: allow defining own shortcuts for commands)
## Prerequisites ## Prerequisites
- Visual Studio 2017/2019 (others might work) - Visual Studio 2017/2019 (others might work)

this will generate `ScrapHack.pyd` in `./build` This will find the Games's installation folder, verify that the version you have is compatible with ScrapHacks and drop the compiled `.pyd` file into the correct folder to be imported
## Usage ## Getting started
- create a `lib` folder next to `Scrapland.exe`
- copy `ScrapHack.pyd` into said folder
- open the ingame console (Ctrl+^) - open the ingame console (Ctrl+^)
- type `import ScrapHack` - type `import ScrapHack`
- type `$help` - type `$help`
- Done!
