#619 chore: get rid of $.param

[pomm0]

fixes #619.

In order to remain backwards-compatible I implemented the Array and Object handler similar as $.param is doing. Could also only use

(new URLSearchParams(queryParams)).toString()

but that is building array and object differently:

const params = {
  user_id: 5,
  comment_id: 1,
  hello: 'world',
  lorem: 'ipsum',
  reply_ids: [1, 2],
  search: {
    author: 'ember',
    topic: 'lts',
    deep: {
      my_array: [99, 77],
      my_value: true
    }
  }
};
const URLSearch = new URLSearchParams(params)
const jquery = $.param(params)
decodeURIComponent(URLSearch)
decodeURIComponent(jquery)

Hey, this looks great! I'll take a closer look on it this weekend. Thank you.
