fromSketchJSON is broken
It's possible I'm lookin in the wrong place but it looks like this line didn't get updated to the new function name: https://github.com/sketch-hq/SketchAPI/blob/e794c0e4a1961b2cad0f8c6d1ef37b7de3a54ab5/Source/dom/export.js#L236

As far as I can tell
 
`MSJSONDictionaryUnarchiver.unarchiveObjectFromDictionary_asVersion_corruptionDetected_error` was updated to `MSJSONDictionaryUnarchiver.unarchivedObjectFromDictionary_asVersion_corruptionDetected_error` in Sketch 64. 4  


Isn't a major goal of this API, to ensure minor internal changes don't break the plugins? It does look like there is a test for this API function, I'm confused how something like this could slip through.
