From cca9e8feb4b8c0638147e330cd7151bddb150c70 Mon Sep 17 00:00:00 2001
From: Artyom Kazak <yom@artyom.me>

Subject: MIME cleanup.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

  * Create a type synonym for MIME type (instead of `String`).
  * Add `getMimeTypeDef` function.
  * Avoid recreating MIME type `Map`s every time.
  * Move “Formula-...” case handling into `getMimeType`.
