Support for read/write streams

[MarkMurphy]

I'm looking for a method to read a file in chunks by specifying a start and end offset similar to that of node's fs.createReadStream method:

options can include start and end values to read a range of bytes from the file instead of the entire file. Both start and end are inclusive and start counting at 0. If fd is specified and start is omitted or undefined, fs.createReadStream() reads sequentially from the current file position.

An example to read the last 10 bytes of a file which is 100 bytes long:

fs.createReadStream('sample.txt', {start: 90, end: 99});

This would allow me to implement a resumable upload interface so that I can take advantage of API's like those from Dropbox, YouTube, AWS, Vimeo, etc. and the TUS protocol
