As mentioned by @d-a-v #6537 (comment)
Update EEPROM description with mention of current implementation limitations
Move ESP_EEPROM to Other Libraries, update description from upstream README
Add https://github.com./xoseperez/eeprom_rotate to Other Libraries as an alternative
Note:
Both libraries depend on #6543
ESP_EEPROM is reimplementing EEPROM class, so the default address would be different from the original library when upgrading to 2.6.0 (for example, using 4m 1m spiffs address is shifted by 1 sector)
Rotate library only uses it for automatic calculation, which user can override. Default ("last") sector is calculated by subtracting 5 sectors from ESP::getFlashChipSize()
