  Injects the ES6 maps support into the Elixir compiler.

  This module does nothing more than calling `Es6Maps.load/0`, causing the ES6 maps support
  to be injected into the Elixir compiler from that moment on.

  It should be added as the first in the list of `:compilers` in `Mix.exs`:

          compilers: [:es6_maps | Mix.compilers()],
