Hi there, I'm trying to use MetadataExtractor on an input that is being streamed over the network. I've implemented a System.IO.Stream subclass that reads data from the network and buffers data that has already been read to allow seeking to work.

Unfortunately, MetadataExtractor seems to read in the entire file before processing any of the metadata. It looks like it might be this line that is the culprit:

https://github.com/drewnoakes/metadata-extractor-dotnet/blob/master/MetadataExtractor/Formats/Tiff/TiffReader.cs#L67

I note that there is already a comment there about this exact issue with a TODO on it. Is there some way to fix this without breaking anything? Alternatively, how about adding an option to allow for stream-based processing and just skip that check when it's set?
