Display undecoded byte values in elm app debugger

[coballast]

Not sure if this is the appropriate place for it, but if you store a Bytes value on your elm model without decoding it, in the debugger (when you compile it with --debug) it displays with a pair of empty curly braces. I had to check the length explicitly to verify the data was there.

This is very confusing! Maybe we can display it like a list of integers or like a hex dump or something?

I would gladly take a swing at this if someone can point me where to look in the code.
