Set multiple registers using json in POST request

[groupmsl]

Added POST functionality which allows a json structure to set multiple registers. Can add more functionality to POST if wanted in future

Example json:

{
    "inverterId": "EGM3N7K06U",
    "startRegister": 1100,
    "values":
    [
        {
            "value": "0105",
            "type": "time"
		},
		 {
            "value": "0655",
            "type": "time"
		},
		 {
            "value": 1,
            "type": "dec"
		}
	]
}
