Create a firmware image file that can be copied byte-for-byte to an SDCard

## Usage
mix firmware.image [my_image.img]
If not supplied, the output image file will be based off the OTP application

## Example
```
# Create the image file
mix firmware.image my_image.img
# Write it to a MicroSD card in Linux
dd if=my_image.img of=/dev/sdc bs=1M
