b3dsdf v0.8.0

At this point all existing 2D sdfs from Inigo Quilez should already be adapted (including the one I missed from previous additions - oriented box). This update adds 5 new 2d SDFs, 4 new 3D SDFs and the hexagon grid(new tiling category).

Since the Volume Cube node has been added (see README.md for more details) it is now possible to use most of the nodes included in this pack in geometry nodes. There's no plans to port the nodes but a converter can be used. However it does motivate me a little in adapting new nodes a bit faster :D

While that there's not a lot of 3D SDFs in this pack it is still possible to utilize 2D ones by generating 3D SDFs from them via vector operators such as extrude / spin (vector operators). See this shadertoy or IQ's site (Revolution and extrusion from 2D) for more details how they work.

The Wiki is still largely a work in progress but most of the following should already have image examples (mostly 2D ones).
