Integrate The Diannex Compiler

[PeriBooty]

One of the goals of this project is to provide everything you need to programmatically get Diannex up and running. Currently, to actually get Diannex binaries to use with what we have currently, you must download/build the compiler at Rupitian/diannex and compile a dx script file using it.

However, the compiler is old, it's had some improvements and bugfixes over the years, but it can certainly use a modern C++ touch-up.
Additionally, we should allow for the ability to compile scripts programmatically, which would mean separating out the actual compilation functionality, and making the actual compiler program a wrapper around the compiler library.

So that leaves the following tasks:

• Port Diannex Compiler #10
• Split Compiler Functionality and CLI #11
• Update Diannex Compiler to C++20/23 #12
• Add Unit Tests and Documentation to The Compiler #13
