vg_errortools - Small error utilities

This crate comprises mainly helpers for generating fat io errors - errors which carry the path of the file it failed with them. It solves the problem with not knowing which file was being processed in async/await powered logged utilities. Be aware, that the fat errors are cloning a PathBuf to store the affected file.

For more comfort in main functions a MainError is provided with a blanket implementation to allow using all errors with the ? Operator.

It's no rocket-science, but convenient.
