JSON decoder does not decode objects accurately if there is a space between the key and the colon

[aaronlink127]

This code sample shows the issue proper

local json = require("pluto:json")
print(dumpvar(json.decode('{"hello": "world"}'))) -- { ["hello"] = string(5) "world", }
print(dumpvar(json.decode('{"hello" : "world"}')))-- {}

I would expect the decoder to decode these the same, but it does not.
