Selects a sub-string from the target string based on selected indices. The indices are 1-based. If the end index is omitted, it returns the rest of the string. One can also specify negative indices, in which case the substr is selected by counting from the end of the string.
{{str sub ×new|target_string|start_index|end_index}}
