reserve 1MB of PSRAM for camera framebuffer on esp32s3-eye

Browse Source 
.. this setting can be overridden with a bigger or smaller value in
CIRCUITPY/.env but 1/8 of PSRAM seems like a good initial value. It's
enough to store a single 800x600 or 640x480 RGB565 frame, or multiple
smaller frames such as 320x240.
