As mentioned in #207, currently, onBeforeUpload will called on each chunk upload, which could raise potential performance drop if some expensive operation is contained in onBeforeUpload. Would be great to support callback which would only execute once, either by change the current onBeforeUpload or add something like onInitiateUpload.
