Update to ESP8266HTTPClient.cpp for no Content-Length (#7691)

Browse Source 
Response bodies are ignored when _transferEncoding == HTTPC_TE_IDENTITY and there is no Content-Length header.  The added code here fixes that issue.

Add logic to writeToStreamDataBlock to only read what's available so as to avoid timeout, and adjust formatting.
