fix(output): compare line numbers while consolidating

without comparing line numbers we do not detect two blocks of errors
with the same error message that are next to each other in output, but
their originating sections are separated by error-free lines

incorrect example:
    multiple-wrong-indentations.txt:
            2-7: Wrong amount of left-padding spaces(want multiple of 10)
    6 errors found
    1 files checked

correct example:
    multiple-wrong-indentations.txt:
            2-4: Wrong amount of left-padding spaces(want multiple of 10)
            8-9: Wrong amount of left-padding spaces(want multiple of 10)
    6 errors found
