deno 1.24.2

Probably due to an recent internal update of naga/wgpu in deno. I will try to get around to fixing it and any other wgsl errors when i get back from my vacation.

@eliassjogreen thank you for the fix but /x/netsaur is broke now.

error: Module not found "https://raw.githubusercontent.com/denosaurs/neo/main/backend/util.ts".
    at https://deno.land/x/netsaur@0.1.1/deps.ts:6:28

Can you publish a newer version?

[eliassjogreen]

This is an issue with Netsaur being unstable and not using the neo api directly. @load1n9 mind looking into this?

[load1n9]

Webgpu in netsaur is still unstable and we're working on fixing that, will look more into it when I get home in 2 weeks
