VALUE attribute has the wrong JSON types

[jangxx]

According to the OSCQuery proposal, the values in the VALUE attribute array should have JSON types matching their data types, i.e. numbers for floats and int, true and false for booleans, etc.

Looking at the values returned from the VRChat client, the library does not honor this, since it serializes all values to strings. For example:

{
    "test_param1": {
        "DESCRIPTION": "test_param1",
        "FULL_PATH": "/avatar/parameters/test_param1",
        "ACCESS": 3,
        "TYPE": "T",
        "VALUE": "False"
    },
    "test_param2": {
        "DESCRIPTION": "test_param2",
        "FULL_PATH": "/avatar/parameters/test_param2",
        "ACCESS": 3,
        "TYPE": "f",
        "VALUE": "0"
    },
}

@jangxx - I'm marking this as complete, let me know if you think we're still missing something.
