what are the differences with vibe.data.json?

[timotheecour]

here's one: vibe.data.json.parseJsonString accepts trailing commas, but stdx.data.json.toJSONValue does not

{
"a":"b",
}

This is an age old bug in vibe.data.json, I'm really surprised that it still exists, but it seems that there has never actually been a ticket for this. I've opened one now and will push a fix shortly: vibe-d/vibe.d#1994
