> CB-7862 - the fix for reading files in chunks defined the chunk size as follow:
> FileReader.READ_CHUNK_SIZE = 256*1024;
> I found a bug on iOS that readAsDataURL in CDVFile.m, converting it to Base64 will not work because the chunk size 262144 is not dividable by 3.
> The quick fix will be FileReader.READ_CHUNK_SIZE = (256*1024) - 1
