Update the "get_data_count" function:
Assume an entry named "blog" with data in JSON format:

{"category":1,"name":"first article","slug":"first-article"}

If you want to count the total entries that contain category=1, use:

{{ get_data_count('blog', {'category':1}) }}

General syntax:

get_data_count(key, filter)

- If the filter parameter is empty, this function will return the total number of entries with the name "key"
