Add REPL Uart Ini File Setting Support

OpenMV IDE includes an ini file generator which will let you set board
settings easily from the IDE. Currently, the IDE has support for setting
the WiFi shield up along with adding a REPL Uart.

Anyway, this commit adds support for the OpenMV Cam to parse an ini file
on startup to configure things before starting main.py. WiFi support is
not yet implmented. However, we now have the ability to turn the UART
and put the REPL terminal on it on startup given a setting in the ini
file.

(Why not use boot.py like normal MP? While that is more flxible it's
much harder for the IDE to easily write out settings for you which is
what most users will want to do versus coding this up).

...

The movitation for adding REPL UART support in particular is so that the
OpenMV Cam can be used as a slave processor to IoT type processors like
the ESP32/ESP8266/ParticlePhoton/ElectricImp. In particular, a processor
like the ParticlePhoton can control the OpenMV Cam's reset wire. Wake
the camera up by releasing reset, then send a script to it after it
powers on over the UART. The camera will then run the script, do
computer vision, and report results back over the UART to the
ParticlePhoton. Users can then push new scripts to the OpenMV Cam from
the cloud allowing for semi-flexible firmware fixes for the OpenMV Cam
over low data rate networks.

By setting this feature up the need for OpenMV to offer a WiFi IoT
system is reduced as we can now just be the best camera for everything.

...

Due to... I don't know... ctrl-c doesn't work on the duplicated UART.

https://github.com/micropython/micropython/issues/1568

Not sure how to handle this. I don't want to fix it since it needs to be
fixed by MP upstream. Right now the work around is for the mastering MCU
to just reset the OpenMV Cam when it's done with the system.

That said, this does mean that once you start a script using the Open
Terminal command line system you won't be able to stop the script.
