Not necessary for this PR, but if people start using this tool in CI, they may not want colors.

Yup I thought about this too. I think we need to do a sweep on the commands in another PR to ensure we don't assume TTY, ANSI etc support.

TL;DR
Improves the error messaging when Rust compilation fails during
fastly compute build.Why?
We've had lots of user feedback that the current implementation is confusing as it just returns an error code and no remediation message or help text. It was also not apparent that you could run the command with the
--verboseflag to get the full output from the childcargoprocess which contains the real cause of the failure.What
We now return the full buffered
stderroutput fromcargo buildif the process fails which hopefully gives the user much more information to solve their problem. We also pass the--verboseflag to the child process if supplied giving even more information if required.
