Add modcharting features (using FunkinModchart)

[dotaxel]

This pull request adds modcharting features using FunkinModchart.
Giving the possibility to create modcharts easily through softcoding (scripts) or hardcoding if preferred.

The tool is based on NotITG and the mirin template, by default you have a large number of modifiers to move and rotate the notes in 3D (instead of just 2D) with correct perspective, set custom paths where the notes will move towards, etc.

As mentioned before, you can move notes along Z and rotate them on all possible axes (X, Y, Z). You can also skew them, bend sustained notes along their path, and much more thanks to the rendering system provided by FunkinModchart!

You can set modifier values, or they can be interpolated using easy functions of your choice, at any point in the song using the Events system.

You can create nodes, add aliases for modifier values, create more playing fields with their own modifiers, and even more!

NOTE: Compilation time can be longer due to FunkinModchart's macros.

Modcharting features can be removed by removing the "MODCHARTING_FEATURES" define from Project.xml.

sorry to say but this unfortunately doesn't work currently as Codename uses Haxe 4.2.5, even though we've been planning to update soon, as for now this cannot work

i wont close this PR though just yet

I'll go do that asap (sorry I'm late)

[TechnikTil]

gotta probably do that tmrw

I love this! Just please add some documentation of some sorts, took me like an hour to figure out how it works. (It would also be good for the codename wiki)

There is documentation, it is on the FunkinModchart readme, although I can also add it to the cne wiki if you like.

oh there is??? shit there goes an hour wasted
nah you good, maybe link it when this is merged

Shouldn't the Codename adapter in the funkin-modchart codebase instead?

Furo, since you're fixing something with invisible strumlines crashing, you should do that to funkin-modchart instead of cne repo, it's getting unused, cuz thats for temporary when i forked it

Okay but its going to need a haxelib release but we could still use git for it
