Random resets panic crash

[mano1979]

about every 10 to 15 minutes the code crashes and the esp32 is rebooted. Te histerical laugh almost giving me a heartattack. Crash report is below:

I understand, thx.

I dont want to open new issue just to show how it works (video on YT) and it is related to this issue(crash). Over 8 hours and still working:

E (29403294) alexa: PING
:status: 204

x-amzn-requestid: 021038fffed1de70-00002533-0008e088-71657edca9c72c00-f934d19a-23

The issue is memory leaking on access token refresh:

W (3037612) asio: 96: - RAM left 28808
........
W (23687034) asio: 96: - RAM left 17544

New ping version looks and works way better than last one and which is most important does not cause memory leak. I will try to find time and prepare clean PR with it. Here is how it looks like:

nghttp2_session *session = alexa_session->stream_events->http2_session->h2_session;
nghttp2_submit_ping(session, NGHTTP2_FLAG_NONE, NULL);

Like i promissed there is refactored ping event. PR is ready to merge.
