Add erasure coding. This allows losing some QR codes #20

IMPORTANT: This doesn't work currently. There seems to be a bug in the reedsolo library. It has been reported at https://github.com/tomerfiliba/reedsolomon/issues/34

This required removing the proprocessing step of base64 encoding. Instead, we base64 encode each QR code independently (always). Sadly this does make the data a little less readable while debugging. Closes #2.

Tried unireedsolmon also. Limited to 255 characters, so will only work up to 35K files with default settings.
