* new helper: AutoDiscoverRTCClock, which detects: DS3231 (on i2c addr 0x68), or RV3028 (on i2c addr 0x52)

* repeater and room server: ver bump (v5), now use AutoDiscoverRTCClock
* various Board::begin() now should do Wire.begin(), with custom pin mappings if needed
* examples removed: ping client/server, and test_admin
