Install guide should mention installing SASS

[AnalyzePlatypus]

What happens?

ToggleButton's CSS is written in SCSS. (Source here).

ToggleButton fails upon installation if sass-loader has not been installed in the vue-cli build:

 ERROR  Failed to compile with 1 errors                                                                           

This dependency was not found:
./node_modules/vue-js-toggle-button/src/Button.vue
Module not found: Error: Can't resolve 'sass-loader' in '/node_modules/vue-js-toggle-button/src'

What should happen?

• The docs should mention installing the missing dependencies, as mentioned in the vue-cli docs here: npm install sass-loader node-sass --save-dev

Fix

The docs should be updated with the missing step.
