feat: introduce custom configurations and lint-staged for stashing un…

…staged changes (#72)

BREAKING CHANGE: Changes multiple defaults for `d2-style`, removes the `install` command, adds extendable configs, only executes style checks on staged files by default, and more.

 - `d2-style js apply` no longer stages files by default, use `--stage` to stage fixed files. The intended usage for this function is primarily to apply the js code standards to files in general, e.g. unstaged/staged files or an entire repo.

- `d2-style validate` has changed to by default run `--fix`, and uses lint-staged to only apply code standards to staged files and/or hunks.

- `d2-style validate --all` no longer exists, validate only operates on staged files and is intended to be used as a pre-commit check. Use `d2-style js check` or apply with `--all` instead.

- `d2-style validate` output has changed. It no longer gives detailed information during a run. It only prints errors when it fails.

- `d2-style js install` has been removed, and the clean-up functions have also been removed.

- `d2-style setup` no longer installs `all` by default, instead prints available groups when command is run.

- It is now possible to stage hunks (`git add -p`) and only style check those hunks.

- It is now possible to extend configuration for lint-staged, eslint, etc.

- Husky hooks included out of the box with `d2-style setup git/husky`
