[sokra]

napi provides a tokio runtime. Could we use that instead of creating a new one?

[kdy1]

@sokra We need to move operations like cloning the options slice to the main JS thread if we want to do so.

• We can't use Buffer from the inline future because it's not Send. So we need to parse option from the main thread and pass something that is Send to the async future.
• We can't use AbortSignal anymore

[kdy1]

Fixed.
