Enhancement: Ability to use custom uploader

[jaskiratr]

It would be helpful to be able to modify sendToServer(file) in order to handle file upload manually.
I'm trying to upload the file to Firebase Storage, which does not use POST request. Documentation

What would be the best way to expose sendToServer() as an option to handle the upload logic?

I've modified the function as below:

sendToServer(file) {
    // Handle custom upload
    if (this.options.customUploader) {
      this.options.customUploader(file, dataUrl => {
        this.insert(dataUrl)
      })
    } else {
      const url = this.options.url || 'your-url.com',
        method = this.options.method || 'POST',
        headers = this.options.headers || {},
        callbackOK =
          this.options.callbackOK || this.uploadImageCallbackOK.bind(this),
        callbackKO =
          this.options.callbackKO || this.uploadImageCallbackKO.bind(this),
        fd = new FormData()
      fd.append('image', file)

      const xhr = new XMLHttpRequest()
      // init http query
      xhr.open(method, url, true)
      // add custom headers
      for (var index in headers) {
        xhr.setRequestHeader(index, headers[index])
      }

      // listen callback
      xhr.onload = () => {
        if (xhr.status === 200) {
          callbackOK(JSON.parse(xhr.responseText), this.insert.bind(this))
        } else {
          callbackKO({
            code: xhr.status,
            type: xhr.statusText,
            body: xhr.responseText
          })
        }
      }

      xhr.send(fd)
    }
  }

Let me know if you find this useful for general use. Happy to work on a pull request.
Many thanks for providing the plugin!
