JsonVariant::size()
Description
If the JsonVariant points to an object, JsonVariant::size() returns the number of key-value pairs in the object (same as JsonObject::size())
If the JsonVariant points to an array, JsonVariant::size() returns the number of elements in the array (same as JsonArray::size())
In all other cases, JsonVariant::size() returns 0
Internally, this function walks a linked-list to count the elements, so its time complexity is O(n).
