Allow ignoring empty structs

[bkmeneguello]

A common idiom in Go is creating empty structs instead of using other constructs, like:

• x := Y{}, instead of var x Y
• x := &Y{}, instead of x := new(Y)

But this linter complains about that. Could be an option to "ignore empty struct initializations"?

Hi Bkmeneguello. I'd really love the same feature too! I had a go at putting together a pull request for it if you want to try it out. https://github.com/GaijinEntertainment/go-exhaustruct/pull/118
