Subject: [fix] HTMLParser: undocumented not implemented method

In python versions <py3.10 there is an issue with an undocumented method
HTMLParser.error() [1][2] that was deprecated in Python 3.4 and removed
in Python 3.5.

To be compatible to higher versions (>=py3.10) an error method is implemented
which throws an AssertionError exception like the higher Python versions do [3].
