1.1.1-netcore3.1

• Fixes Crc16.ComputeChecksum ( Crc16Algorithm.Dnp, array, start, length ) computations which previously did not use start or length but instead computed checksum over the entire array
• Fixed underlying calculations to correctly check bounds at edge cases
• Fixed unit test for CRC 16 DNP to use correct checksum for the length less than start test scenario
