An ESP32 nature camera

To keep power usage low, we should trigger it on movement detected with a PIR sensor. That could be an interrupt waking it from deep sleep, but could also use this approach to power up the device from the sensor
The default HTML interface is good for getting the camera positioned correctly, so having something like that to set up the options would be good.
The HTML is actually served as a gzipped blob, from index_ov2640_html_gz
in camera_index.h
.
The ESP32-CAM board has a micro-SD reader on board. We should be able to save images there as well as serve them over HTTP
As well as being triggered by a PIR sensor it would be good to be able to set an interval between photos for a timelapse.
We should store the settings in flash (there's a new API rather than EEPROM), so that we remember what's been set up from one boot to the next
The web UI is really handy for positioning the camera in the right place, but will be power hungry the rest of the time.
Would be good to have a way to easily enable/disable it.
When the SD card is in use, the flash LED turns on.
In theory, switching the SD card to 1-bit-mode will fix that, but it didn't seem to with a quick test (setting SD_MMC.begin("/sdcard", true)
in the sketch)
