Add stack traces to errors

[matejpavlovic]

Some useful, but potentially outdated links:

• https://pkg.go.dev/github.com/pkg/errors: Library to create errors throughout the code.
  It is old and a third-party one but has the needed functionality,
• native Go errors library (does it support stack traces?)
• errstack package.

It looks like this is what we need: https://github.com/go-errors/errors
