Allow the user to define a specific bin output directory

[Telokis]

The current behavior of sw is to output bin files to .sw/out/<hash>/.
This is not ideal because the user doesn't know the value of <hash>. We have to look at the build output to see where the file was outputted.

My suggestion is to add a CLI option like --out-dir which could be set to any directory (existing or not). sw would then output everything there.
This could also be specified inside the sw.cpp, allowing for consistent setup without relying on the user to remember to use the CLI option.

We could also have both a CLI option and a sw.cpp config but the CLI option takes precedence, for example.

Added sw build --output-dir bin.
Update sw and try it!

Works perfectly, thank you!

Are you considering the other part of the issue?

This could also be specified inside the sw.cpp, allowing for consistent setup without relying on the user to remember to use the CLI option.

Such thing was earlier (also in cppan). It is disabled at the moment.
