server occasionally returns edges that aren't valid ints

[Phelimb]

e.g.

ATGCGTTATATTCGCCTGTGT
{
"key": "ACACAGGCGAATATAACGCAT", "colours": [1],
"left": "AT", "right": "A",
"edges": "a3",
"links": []
}

I'm not sure if this is intended behaviour though?

Edge coding is explained here in the wiki:

https://github.com/mcveanlab/mccortex/wiki/McCortex-HTTP-Webserver#hexadecimal-edge-coding

It's a compact way to specify each samples' edges using only two characters per colour.
