Last chunk size too large

[depiction]

If multiple chunks are created, the last chunk is always larger than the chunk size set in the config.

var r = new Resumable({
    target: function (chunk) {
        console.log(chunk)
        return '/test/'
    },
    query: {},
    maxChunkRetries: 2,
    simultaneousUploads: 1,
    chunkSize: 1 * 1024 * 1024 // 1MB
});

The chunk size is 1MB or 1048576 bytes.

I uploaded a 2.5 MB file, but only two chunks were created. Below are the console logs returned from the target function. The first chunk size matches the chunk size set in the config, but the second chunk size is too large.

I also uploaded a 1096 MB file and all the chunk sizes matched the chunk size set in the config, except the last one, which was too big.
