x.json2: decode array

[felipensp]

Fix #21168

Added generic way to decode a JSON array string into a array of generic type.

import x.json2


pub struct Value {
	value string
}

pub struct Value2 {
	value string
}

fn main() {
	println(json2.decode_array[Value]('[{"value": "abc"}, {"value": "def"}]')!)
	println(json2.decode_array[Value2]('[{"value": "abc"}, {"value": "def"}]')!)
}

Why not making it part of decode?

Why not making it part of decode?

Must investigate a way to decode []T to T, it seems we can't do it at the moment. This was the point.
