Title: writeFileAtPath does not check minizip return codes

The results of calling zipOpenNewFileInZip, zipWriteInFileInZip, and zipCloseFileInZip are not checked. Ignoring these return codes can cause zip file creation to fail or corrupt silently.

I found these unchecked calls in:
```objective-c
- (BOOL)writeFileAtPath:(NSString *)path withFileName:(NSString *)fileName
- (BOOL)writeData:(NSData *)data filename:(NSString *)filename
```
