Please rollback PR 306!

Would it be possible to rollback PR #306, as it breaks this library on ESP8266?

This PR uses an ESPmDNS library, designed for ESP32 only.

If mDNS support is really needed (IMHO, mDNS suport has to be decided in setup() call, not embeded into libraries), it would perhaps be better using ESP8266mDNS. and adding some #define to allow people that don't want to use mDNS to disable it (even if I do continue to think that this should be done into setup(), not in low level library)

Thanks in advance,

The current implementation doesn't even seem to work, this has to be reverted asap

Sorry, I did the rollback, but forgot to confirm the merge. Should hopefully be ok now.
