v3.6.0

• ADD: support for new features from Tailwind CSS v3.1.0

  Custom dark class, .grid-flow-dense, .text-start, .text-end, .mix-blend-plus-lighter, .border-spacing...

• BREAKING CHANGE: groups, groupByResponsive, officialSorting and prependCustom are deprecated ☠️.
  The official sorting from prettier-plugin-tailwindcss is always used by classnames-order.

  This was required in order to support classnames generated by plugins.
