Add Last Assert to str$..$

Add on last assert statement to

str$\_$to$\_$seconds that calls iso$\_8601.$ Again,

error messages are optional and are not

required. To test your assert statement,

you will need to call the function

str$\_$to$\_$seconds in the interactive shell.

Calls like str$\_$to$\_$seconds$(\text{'}1$:$301$:$12\text{'})$ or

str$\_$to$\_$seconds$(\text{'}12$:aa:$12\text{'})$ should crash

with an AssertionError if you did it

properly.

You may run this test multiple times.
