+    A helper class for parsing the byte stream input.
+
+    The output of the model will be in the following format:
+
+    b'{"outputs": [" a"]}\n'
+    b'{"outputs": [" challenging"]}\n'
+    b'{"outputs": [" problem"]}\n'
+    ...
+
+    While usually each PayloadPart event from the event stream will
+    contain a byte array with a full json, this is not guaranteed
+    and some of the json objects may be split acrossPayloadPart events.
+
+    For example:
+
+    {'PayloadPart': {'Bytes': b'{"outputs": '}}
+    {'PayloadPart': {'Bytes': b'[" problem"]}\n'}}
+
+
+    This class accounts for this by concatenating bytes written via the 'write' function
+    and then exposing a method which will return lines (ending with a '\n' character)
+    within the buffer via the 'scan_lines' function.
+    It maintains the position of the last read position to ensure
+    that previous bytes are not exposed again.
