slice
--------------
Return a new `File` object, for which `FileReader` returns only the
specified portion of the file. Negative values for `start` or `end`
are measured from the end of the file. Indexes are positioned
relative to the current slice. (See the full example below.)
__Parameters:__
- __start__: The index of the first byte to read, inclusive.
- __end__: The index of the byte after the last one to read.
__Quick Example__
var slicedFile = file.slice(10, 30);
__Full Example__
var slice1 = file.slice(100, 400);
var slice2 = slice1.slice(20, 35);
var slice3 = file.slice(120, 135);
// slice2 and slice3 are equivalent.
