iris compat

[Caffeinew]

I basically just threw stuff at rendering code untill something worked. Looks like iris doesn't like lightmaps in shaders, so i'm just emulating a similar look with alpha.

Alternatively different render code can be used when iris is active

Also, I think with some changes the atomic thingie laser can use the basic laser rendering fn instead of particle one, but that's like actual work, so I cba.

While testing myself I noticed that while it didn't like the lightmap shader it did accept the tex lightmap one

Neither getPositionColorLightmapShader or getPositionColorTexLightmapShader work for me for particle render for atomic laser.

POSITION_COLOR_LIGHTMAP does work for the other ones tho

In my testing I had to change the vertex of the ParticleRenderType in the ParticleBeam class away from Particle

A wip video showing it somewhat working in my testing but not fully as it seemed to stop 4,5 blocks outwards

But your lasers look better than my lasers did during my attempts

The color being wrong is probably an AA bug but might as well fix it if possible ;)

Wonderful! As someone who can’t even look at this game without shaders, I really appreciate this.
