feat: allow collecting raw output from sidecars

[niusia-ua]

In the tauri_plugin_shell::process::Command, we have the output method which automatically collects all output from the sidecar command. The issue with it is that it inserts \n after each received chunk. In case of handling raw output (i.e. binary output; for example, images, PDFs, etc.), this behavior breaks the received buffer.

It would be nice to have a boolean parameter or a separate method for collecting the output without inserting \n between chunks.
