Noscrape from ArrayBuffer

[schoenbergerb]

Discussed in #44

Description

Extend the Noscrape constructor to allow passing the font as an ArrayBuffer | SharedArrayBuffer in addition to the current option of passing it as a path (string).

Expected Result

• The Noscrape constructor can be called with a path as a string.
  The font is then loaded by the loadSync function of opentype.js.
• The Noscrape constructor can be called with a buffer ArrayBuffer | SharedArrayBuffer.
  In this case, the parse function of opentype.js should be used.
