[F3D] Serializable node library format concept

[Lilaa3]

This would allow fast64 to have 0 binary blobs (outside images anyways).

1. No more binary blobs
2. Real diff when making updates to the nodes
3. The hashing system, which means that if this was merged there would never be another f3d mat version (not for nodes anyways)
4. Repeated reloads on changing files causing load times to spike no longer happen
5. Hopefully no more need to boot into a specific version to work on the nodes.

looks very interesting!
I'm surprised this is faster than a library blend, how did you time that?

[Lilaa3]

@Dragorn421 At least with my latest commit and in blender 4.1 oot level imports go by quickly (tho i didnt time it but i vaguely know how long main takes)
(That said existing blend updates still feel slower than they should be realistically (recreate shader nodes is significantly faster??))

[Lilaa3]

I figured out a way to boost performance, and its literally deleting the existing node group if we are gonna update materials anyways lol

Timings for importing OoT's deku tree map:
on main: 30-40 seconds
this PR: 50-60 seconds

much better! wouldn't be a blocker for merging, but doesn't really back "it's faster"

uh, still? guess I'll take it, material creation FEELS faster tho, maybe I just imagined it

Timing the "create f3d mat" operator (ignoring the first time clicking the button):
on main: 0.5 seconds
this PR: 0.9 seconds

1. open blender
2. create mesh object
3. click "create fast3d material" and ignore time for that first click
4. click "create fast3d material" a bunch of times and draw a number from that

Anecdotally, this feels a lot faster on 4.5 (ignore previous statement I am dumb)
Works for me.

I'll leave it up to someone OOT to merge based on their feelings of the value of speed

Dragorn felt it wasn´t worth it, so we shouldn´t merge unless everyone agrees. I like it for streamlined upgrades, the real diff and letting you make changes in any version. Dragorn dislikes it because the speed is either equal to or slower.
