Remove gogit and major refactoring (#2)

* Fix typo in readme

* Reimplement all git methods without go-git

* Rename repo pkg to git, add gitconfig methods

* Improve tests for configuration reading

* Rename package file to io and move RepoFinder there

* Refactor printers

- Remove smart printer
- Decouple printers from git repos with interfaces
- Update printer functions
- Remove unnecessary flags
- Add better remote URL detection

* Update readme and go.mod

* Add author to git commit in tests

Otherwise tests will fail in CI.

* Install git before running tests and don't use cgo

* Add better error message, revert installing git

* Ensure commit message is in quotes

* Set up git config before running tests
