\.br\ is not properly serialized leading to ParseMessage failure about hl7-dotnetcore

hi @justinfalk,
Your sample message doesn't have the required header segment (MSH). That would never parse correctly.

Sorry, that was a result of hastily deidentifying the message. The message still fails due the the serialization problem I referenced above. I went and edited the original issue to add the missing MSH. Thanks.

Here's a much narrower example of the bug in the Encoding function

        [TestMethod]
        public void TestEncode()
        {
            var text = @"Some Text\.br\";
            var decoded = new HL7Encoding().Decode(text);  // <BR>
            var encoded = new HL7Encoding().Encode(decoded); // Still <BR>

            Assert.AreEqual(text, encoded);
        }

Actually, this appears to be resolved in 2.26. I was using an older version.

Looks like this fix corrects the issue: #82
