1.4.0 - Improved scan engine, fix for HEOS, new object member "protInfo"

The struct soapObject_t by default has a new string member protInfo. If it is not needed and memory is limited then use build option NO_PROTOCOL_INFO. The XML scan engine (MiniXPath) has been improved, resulting in reduced scan times. Fix for a HEOS media server running on a Denon AV-Receiver.

1.3.2 - Fix for a media server running on an Orange France router

Minor code change to allow chunked file/stream data which was reported by an user of an Orange France router. The device seems to be a Livebox from SoftAtHome. The media server is reported as "DMS V1.6.55".

1.3.1 - New function + example, minor bugfix

New function getServerCapabilities() actively queries a media server for it's UPnP content search/sort capabilities.
New example GetServerCapabilities_WiFi.ino makes use of it and log file GetServerCapabilities_WiFi_2-Warning.log shows the capabilities of a few real world media servers.
Bugfix in file SoapESP32.cpp, lines 986-988. Previous versions forgot to close the socket in this very rare error situation.
