Suggest to add an option to output the full stack log to the file

[h4x3rotab]

When running devphase stack everything is on the screen. I can redirect it to a file for debugging like this:

yarn devphase stack |& tee tmp/stack.log

However when running e2e test, it will be hard to get the output. This is especially useful when debugging with some weird case (e.g. wasm contains float point operations, causing the code rejected by pruntime).

It's a low priority feature request though
