Pull in OPEnSLab-OSU's SSLClient v1.6.11

[marcelstoer]

Apparently your code uses/is based on OPEnSLab-OSU's SSLClient v1.6.9. That version has issues like the one commented on here https://github.com/khoih-prog/EthernetWebServer_SSL/blob/main/examples/MQTTClient_SSL_Auth/MQTTClient_SSL_Auth.ino#L72 (OPEnSLab-OSU/SSLClient#9).

Pulling in the changes for 1.6.11 would allow you to remove the work-arounds: v1.6.9...v1.6.11
