fix: bumped bytemuck and itoa

[schell]

This fixes an error where spirv-builder-cli fails to compile because of unresolved dependencies on bytemuck and itoa.

Here's my output when trying to compile renderling, which targets rust-gpu 6e2c84d:

@tombh I thought I had already added you as a maintainer, but I guess not. I've sent you an invite. Once you've accepted I can request your review here :)

[schell]

renderling seems to build just fine without these changes on your your branch for

• Support CI tests for old rust-gpu versions #41

...so maybe these changes are extraneous?

[schell]

Ah, yes, I see your branch has bumped these as well, though not as far as my changes.

[tombh]

Just a quick reply to say I got the invitation, thanks. And that I'm trying to remember how we support this Cargo.lock across all our supported spirv-std versions? But of course, if the CI tests are passing then there's nothing urgent to worry about. And of course updating these deps even further should be fine.

[schell]

I'll rebase and run with the new CI improvements 👍
