Compiler warnings for MailSender

I've been using MailSender with an ESP32, and it works perfectly, but the compiler in the new Arduino IDE 2.0 throws a warning about repeated #defines for EMAIL_NETWORK_CLASS. It's in EMailSender.h, lines 222 and 165. The defines are identical, just repeated because of the #ifdef logic. Just an FYI for you. Thanks for the library...Jack
