Motivation:

Length-encoded integers should be handled correctly, especially those larger than Long.MAX_VALUE. See also #39.

Modification:

Add code comments to explain how to handle the length encoded integer.
Correct LargeFieldReader.readSlice() method, it should use the length as an unsigned long.

Result:

LargeFieldReader.readSlice() should now work correctly for fields those size is greater than 2⁶³-1
