[just-omit] webpack import error

When trying to import packages I see an `Uncaught TypeError: just_omit__WEBPACK_IMPORTED_MODULE_0___default(...) is not a function` error when doing `import omit from 'just-omit'

Using:
`"just-omit": "^2.2.0"`
`"webpack": "4.41.5"`
`"react-scripts": "3.4.0"`

Not sure what's causing the import not to work on this version of webpack, I believe it doesn't support ES6 but as far as I can tell this package doesn't need ES6 it should be fine on ES5
