Do you know how TinyJSON serializes 64 bit integers? We should probably maintain symmetry.

It serializes long as unquoted.

This test passes:

[Fact(Timeout = TestsUtil.TIMEOUT_MILLISECONDS)]
public void ToJson_LongToJson()
{
    var obj = new Dictionary<string, long>();
    obj["key"] = 1234567891234;
    var json = obj.ToJson();
    
    Assert.Equal("{\"key\":1234567891234}", json);
}
