fix: changing directory structure to idiomatic go directory format

[tjgurwara99]

As the title suggests, I wrote this PR because there are some things within this repo that are not idiomatic to Go style of writing software. I changed the directory structure such that all the underscore characters _ are removed from the package naming as well as changed some code around so that it is more readable and learners can use their own go code to experiment with these structures - main reason why I did a previous restructure #266

Also fixed one of the LGTM analysis alerts which gets this repos alerts to zero.

NOTE: The action will continue to fail until the PR #338 is merged and I have resolved its conflicts. So I'm waiting for that PR to be merged and will continue with this afterwards.

UPDATE: Done
