only % branch and % funcs are ignored, not % stmts or % lines

when I start a file with `/* c8 ignore start */` and I don't have any other ignore comments (behavior is the same with or without `/* c8 ignore end */` at the end of the file) C8 only ignores the lines when measuring branch and functions, but not when measuring statements or lines:

the files in question are boilerplate files whose testing is largely covered by the testing done by the maintainers of the library I'm using so I would like to exclude them from my line and statement code coverage requirements
