Uint8Array image data support documented, but throws exception

[ronny1982]

Regarding documentation the addImage() method accepts Uint8Array.
However when using image data as Uint8Array the call to getImageFileTypeByImageData() fails.
This method assumes a binary-string? (at least no support for Uint8Array) and tries to call .charCodeAt() on the image data.

Either getImageFileTypeByImageData() shall support Uint8Array or
addImage() shall call getImageFileTypeByImageData() with the correct converted image data type.
