Sends the given binary data to the browser. This method is similar to
 <tt>render plain: data</tt>, but also allows you to specify whether
 the browser should display the response as a file attachment (i.e. in a
 download dialog) or as inline data. You may also set the content type,
 the file name, and other things.

 Options:
 * <tt>:filename</tt> - suggests a filename for the browser to use.
 * <tt>:type</tt> - specifies an HTTP content type. Defaults to 'application/octet-stream'.
   You can specify either a string or a symbol for a registered type with <tt>Mime::Type.register</tt>, for example :json.
   If omitted, type will be inferred from the file extension specified in <tt>:filename</tt>.
   If no content type is registered for the extension, the default type 'application/octet-stream' will be used.
 * <tt>:disposition</tt> - specifies whether the file will be shown inline or downloaded.
   Valid values are 'inline' and 'attachment' (default).
 * <tt>:status</tt> - specifies the status code to send with the response. Defaults to 200.

 Generic data download:

   send_data buffer

 Download a dynamically-generated tarball:

   send_data generate_tgz('dir'), filename: 'dir.tgz'

 Display an image Active Record in the browser:

   send_data image.data, type: image.content_type, disposition: 'inline'
