Add value table data to JSON output

[TimJTi]

Thank you for this project it has saved me a lot of work!

I am using the JSON output (for now) and need value table data so have added this myself in a fork of this repo and it works well I think. Here is a sample of the output:

		{
			"name" : "Message_60Eh",
			"id" : 1550,
			"extended" : false,
			"dlc" : 8,
			"signals": [
				{
					"name" : "gear",
					"startbit" : 23,
					"bitlength" : 16,
					"endianess" : "motorola",
					"scaling" : 1,
					"offset" : 0,
					"minimum" : 0,
					"maximum" : 10,
					"signed" : true,
					"floating" : 0,
					"units" : "",
					"values" : {
						"0" : "Unknown ",
						"1" : "Reverse",
						"2" : "Neutral",
						"3" : "First",
						"4" : "Second",
						"5" : "Third",
						"6" : "Fourth",
						"7" : "Fifth",
						"8" : "Six",
						"9" : "Seventh",
						"10" : "Eighth"
					}
				},
				{
					"name" : "fuelComp",
					"startbit" : 39,
					"bitlength" : 16,
					"endianess" : "motorola",
					"scaling" : 0.1,
					"offset" : 0,
					"minimum" : 0,
					"maximum" : 100,
					"signed" : true,
					"floating" : 0,
					"units" : "%",
					"values" : {}
				}
			]
		},

I am happy to submit this as a PR if you'd like me to?

Sure! Set the target to testing when making the PR instead of master, I'll have a look at it. It helps if you add a DBC file as well demonstrating the data you used and what it should look like. I'll close this, and we can talk on the PR if we need to.

Will do. Do you want the DBC file as a second commit (to which project folder?), or attached in some other way?

Put it in a commit in the top level folder, it doesn't need to be a separate one.
