Feature request: capture all the stdout/stderr from crytic-compile/slither/echidna and save it at every iteration

[ggrieco-tob]

In the current audit, I'm getting some stderr messages from crytic compile that break the console output:

ERROR:CryticCompile:Error HH12: Trying to use a non-local installation of Hardhat, which is not supported

This is a non-fatal error, but the console is disrupted.

On top of that, it could be very useful to save the echidna output, in case of some issue (e.g. it can crash because it uses too much memory) or because we want to see the exact output (e.g. events), without re-running a campaign.
