Flash memory layout changes break persistence

[xoseperez]

A flash layout change in 1.8.3 has had an unpredicted and unpleasant consequence of preventing devices from persist and retrieve configuration if they are flashed using OTA and PlatformIO.

Arduino IDE users might not notice this if they are still using Flash layout "1Mb (128K)".

You have two options to fix this:

• Do not use OTA to flash a device with ESPurna 1.8.2 or before with a newer version. Once the version is 1.8.3 or more you can use OTA again.
• Change the build flags in the platformio.ini file, section "common", to:

build_flags_1m = ${common.build_flags} -Wl,-Tesp8266.flash.1m128.ld

Actually, this should not be an issue since EEPROM starts at the same address on both layouts...
