Port to Fabric, Minecraft 1.19.1/1.19.2

[AJahueyM]

I recently added Dynmap to a modded server Im running with some friends and noticed that BlockScan is Forge only. I decided to port it. This is my first exprience with Minecraft modding so if there is any better way to impement certain features please let me know!

Dynmap showing some blocks from "Blockus", which is Fabric only.

Any ideas?

[L1Z3]

Sorry, disregard this--I used the wrong jar! (I needed to run the jar target followed by remapJar in fabric-1.19.1/build.gradle and then use that target jar, not whatever I was using before.)

Thanks so much for your work on this port!!

[Jolain]

Absolute legend. I have issues with a few mods not rendering correctly but otherwise works great, thank you so much.

[Jolain]

Mostly working on AQM2 1.19.2 with , notably Oh The Biomes You'll Go does not export properly.

[AJahueyM]

During the summer I may try to fix these issues

[mikeprimm]

Excellent! I'll give this a look, and we can see about extending on your work!
