Create a RandomAccessBlob instance from a blob that is "readable" and "statable". options can be:

{
  offset: 0, // An optional offset to start reading from in the Blob
}

storage = require('random-access-blob/file')(file[, options])

Create a RandomAccessBlobFile instance from a file that is "readable" and "statable".

{

}

storage.read(offset, length, callback)
