aqua cli can't handle writing to short pipes

[folex]

If you pass output of the aqua to a pipe that doesn't read the whole output, aqua throws write EPIPE error.

Simple way to reproduce is to send any aqua command to head -n1, as in aqua ... | head -n1.

A real-life example is passing aqua getInterface to jq . for JSON parsing. jq detects incorrect JSON, and stops reading. Aqua complains.

Instead, it should handle writing to pipes correctly. As I understand it, if stdout/stderr is closed, simply don't write there.

This is a rather critical bug for a CLI tool, because it makes it impossible to use for automation and scripting.
