Display build process messages to console

[Daniel Makovský]

Hi,

Lately i've been working with rust a lot and one thing is driving me crazy a little during production deploy.

I dont know it it properly works for other (outside compiled) runtimes like c# and Java, but SST hides all output from async executions of cargo-lmabda.

It could be easilly solved by using callback from execAsync and piping it to console. Just how it works with workers just few lines above workers.stdout(input.workerID, data.toString());
Or i guess even directly calling console.log() since thats how internally works eslint implementation in node runtime (i guess).

I could try to implement it later this month if this makes sense.

Anyways just from curiosity, is there a reason execAsync is used ? Using spawn just like in worker process would eliminate problem caused by combination of promisify and callbacks.
