Add aggressive_ignore_whitespace parameter for output comparison

[first-storm]

I am a freshman and was stuck on an auto-test issue caused by a whitespace mismatch for an hour. To address this, I made this pull request.

This pull request introduces a new parameter called aggressive_ignore_whitespace for output comparison.

Local Testing Results

I have tested the changes locally, and here are the results:

test.c

Here is the sample test.c file used for testing:

#include <stdio.h>

int main() {
    printf("Hello   \t  World!  \n");
    printf("Line 2  with space. \n");
    printf("NoSpaceLine3.\n");
    return 0;
}

tests.txt Configuration

Below is the tests.txt configuration file that defines the test cases:

files=test.c
default_compilers = {'c' : [['gcc', '-Wall', '-o', '%']]}

# Test aggressive_ignore_whitespace was disabled
test1 command="./test" expected_stdout="Hello   \t  World!  \nLine 2  with space. \nNoSpaceLine3.\n"
test1 description="aggressive_ignore_whitespace=False (default)"

# Test aggressive_ignore_whitespace was enabled
test2 aggressive_ignore_whitespace=True command="./test" expected_stdout="HelloWorld!\nLine2withspace.\nNoSpaceLine3.\n"
test2 description="aggressive_ignore_whitespace=True"

# Test aggressive_ignore_whitespace=True and ignore_trailing_whitespace=True were both enabled
test3 aggressive_ignore_whitespace=True ignore_trailing_whitespace=True command="./test" expected_stdout="HelloWorld!\nLine2withspace.\nNoSpaceLine3.\n"
test3 description="aggressive_ignore_whitespace=True and ignore_trailing_whitespace=True"

# Test aggressive_ignore_whitespace=False and ignore_trailing_whitespace=True were both enabled
test4 ignore_trailing_whitespace=True command="./test" expected_stdout="Hello   \t  World!\nLine 2  with space.\nNoSpaceLine3.\n"
test4 description="aggressive_ignore_whitespace=False and ignore_trailing_whitespace=True (original)"
