inertia@v0.2.3

This release adds the ability to define custom headers on Inertia requests, thanks to the work of @claudiodekker (#202).

Here is how this is done:

this.$inertia.visit('/users', {
  headers: {
    'Custom-Header': 'value',
  },
})

this.$inertia.post('/users', this.form, {
  headers: {
    'Custom-Header': 'value',
  },
})
