Parsing stops at `\r\n` followed by comment

I ran into this when lustre dev tool's gleam.toml options didn't work.

Minimal reproduction can be found [here](https://github.com/nnuuvv/tom_comments/blob/main/test/tom_comments_test.gleam).

The first test [`with_string_linebreaks_test`](https://github.com/nnuuvv/tom_comments/blob/faa9bb1aef7dbd9232ff83d205d36c12319a6677/test/tom_comments_test.gleam#L12) works as expected.

The second test [`without_string_linebreaks_test`](https://github.com/nnuuvv/tom_comments/blob/faa9bb1aef7dbd9232ff83d205d36c12319a6677/test/tom_comments_test.gleam#L35) fails.
The `toml` string here is how `simplifile.read` returns it.

Start with the minimal reproduction in test/tom_comments_test.gleam, especially with_string_linebreaks_test and without_string_linebreaks_test, and run the failing test. Trace the TOML parser behavior for a \r\n sequence followed by a comment; done means the second test parses successfully like the first.
