getenv: treat a read error like eof
Otherwise, the following would occur:
 * settings.toml is in the process of being written by host computer
 * soft-reset begins
 * web workflow tries to grab CIRCUITPY_WIFI_SSID, but loops forever
   because FAT filesystem is in inconsistent state and file reads error
 * settings.toml write by host computer never completes and the filesystem
   remains corrupt
 * restarting yields a soft-bricked device, because startup reads
   CIRCUITPY_WIFI_SSID again

**CircuitPython** is a *beginner friendly*, open source version of Python for tiny, inexpensive
computers called microcontrollers.

This package contains the "stubs", or type definitions for CircuitPython.  With some advanced
editors and other tools, this information can be identify TypeErrors, AttributeErrors, and other
problems before you deploy your code to a device and can even help autocomplete your code.
