Using 1.19 assets fails

[FireController1847]

Describe the bug
When using 1.19 assets (see below), it attempts to request the following URL, which does not exist:

https://assets.mcasset.cloud/1.19/assets/minecraft/models/minecraft:block/cube_all.json

However, if we rename "minecraft:block" to just "block," it works fine:

https://assets.mcasset.cloud/1.19/assets/minecraft/models/block/cube_all.json

To Reproduce
Steps to reproduce the behavior:

1. Use the "assetRoot" option
2. Set your asset root to the following: https://assets.mcasset.cloud/1.19
3. Attempt to render a "netherite_block"

Expected behavior
No error

Screenshots
N/A

Additional context
I downloaded the embed/model index.html file and manually inserted the assetRoot to the options. This is the URL I used:

index.html?models=block/netherite_block&shadow=false&camera.position=26,26,26&controls=false&controls.rotate=false&controls.zoom=false&controls.pan=false

This issue begins to appear starting at Minecraft 1.16. Minecraft 1.15 works fine.

Tracing further into the code, it appears that post Minecraft 1.15 assets includes the namespace in the asset name which seems to screw up the URLs. I'm implementing a temporary fix on my fork to simply remove these namespaces, but it's definitely jank and wouldn't recommend this as a permanent solution lol
