Remove dependency: `cargo-run-wasm`

[emilk]

cargo-run-wasm seems like a dead crate, with no updates in the last year. It pulls in old dependencies, causing warning on cargo-deny:

      - `safemem::copy_over(slice, src_idx, dest_idx, len);` can be replaced with `slice.copy_within(src_idx..src_idx+len, dest_idx);` as of `rust 1.37.0`.
      - `safemem::write_bytes(slice, byte);` can be replaced with `slice.fill(byte);` as of `rust 1.50.0`
      - `safemem::prepend(slice, vec);` can be replaced with
      
        ```rust
        let old_len = vec.len();
        vec.extend_from_slice(slice);
        vec.rotate_left(old_len);
        ```

we use it to run re_renderer examples on the web right now. It shouldn't be too hard to figure out some other way to do so conveniently

hey i would like to work on this

but from the readme, I found this

This is a temporary solution while we're in the process of building our own `xtask` tools.

so, i am little confused, how can i contribute?

great to hear you want to help out! :) The task here is to remove cargo run-wasm in favor of some other solution that allows running re_renderer's examples easily on the web (that's the only thing we use run-wasm for right now)

i am thinking about wasm-pack, which is more popular and maintained,

but thinking about what would be the great dx, cuz wasm-pack requires to build first and then run it, where run-wasm was straight forward single command which was no-brainer

but will need to create wrapper around it

there is another option also to use something like trunk

what do you think and suggest?

wasm-pack requires to build first and then run it

That's fine, we can always add a command in pixi.toml to do one after the other

what do you think and suggest?

I don't know :) Something simple, with few dependencies
