"""Stressful Subject mission from checkio
The function should recognises if a subject line is stressful.
A stressful subject line means that all letters are uppercase,
and/or ends by at least 3 exclamation marks and/or contains at least one
of the following “red” words "help", "asap", "urgent".
Any of those "red" words can be spelled in different ways -
"HELP", "help", "HeLp", "H!E!L!P!", "H-E-L-P",
even in a very loooong way "HHHEEEEEEEEELLP"
Input: Subject line as a string
Output: Boolean.
Precondition: subject can be up to 100 letters
