Title: Add `error` parameter to `finishWriting…` handler block

Discussed in Pull Request #823.

I added `error` parameter to handler block of method `-[GPUImageMovieWriter finishWritingWithCompletionHandler:`. On successful write, the value is nil, on failure it contains error description.

The error is taken from `error` property of underlaying `AVAssetWriter`.
