> The wasb mimicking of {{getFileBlockLocations()}} uses the length of the file as the
number to use to calculate the # of blocks to create (i.e. file.length/blocksize), when it
should be just the range of the request.
> As a result, you always get the number of blocks in the total file, not the number spanning
the range of (start, len). If this is less (i.e start > 0 or len < file.length), you
end up with some 0-byte-range blocks at the end
