An optional list of extensions to enforce when uploading files.
Note: The extensions and file names will be compared ignoring case.
An optional maximum file size to enforce for each file. This will only be
							used when it is greater than 0.
If the number of files should be limited, set this value to a number
							greater than 0.
Note: This still allows "infinite" files when set to 0 since the
							<input> element should normally be set to disabled if files should not
						be able to be uploaded.
An optional minimum file size to enforce for each file. This will only be
							used when it is greater than 0.
The total number of bytes in the FileUploadHookReturnValue.stats list. This is really just:
const totalBytes = stats.reduce((total, stat) => total + stat.file.size, 0);
					An optional total file size to enforce when the maxFiles option is
							not set to 1.
The total number of files in the FileUploadHookReturnValue.stats.
