Merging this into VSCode-go extension?

[earik87]

First of all, thanks for making this extension! It is super useful.

Are you considering to make this extension a default feature in vscode-go extenstion?

Thank you for your compliment. but I think my code is a bit messy, and the feature and structure is not polished enough. However, anyone is welcome to take some of good parts of this code and PR to the official one.

i took some concept from https://github.com/tkgalk/go-interface-annotations for inspiration
