Library crashes when compiled to WASM with atomics flag enabled

[drewhk]

When compiled to WASM with atomics flag (which flutter rust bridge enables) the library crashes due to

.cargo\registry\src\index.crates.io-6f17d22bba15001f\tinyaudio-0.1.4\src\web.rs:57:14:
called `Result::unwrap()` on an `Err` value: JsValue(TypeError: Failed to execute 'copyToChannel' on 'AudioBuffer': The provided Float32Array value must not be shared.
TypeError: Failed to execute 'copyToChannel' on 'AudioBuffer': The provided Float32Array value must not be shared.

This error is exactly the same as documented in cpal: RustAudio/cpal#656
Fixed here: https://github.com/RustAudio/cpal/pull/837/files

Basically with this flag the generated WASM code uses SharedArrayBuffer, but the copyToChannel only allows Float32Array.

Could you please try the fix? I checked it with the following commands and it seems to work fine

cd wasm-examples
rustup default nightly
RUSTFLAGS="-Ctarget-feature=+atomics,+bulk-memory,+mutable-globals" wasm-pack build . --target=web -- -Z build-std=panic_abort,std
basic-http-server

Works perfectly, thank you for the very quick fix, much appreciated!

Cool, I'll submit a new version on crates.io then.

I've published 0.2.0, closing this as completed.

Many thanks! I owe you a beverage :D
