Review comment:
nit: In Scala, we can use `==` to compare strings. It is a bit more
readable than using `equals`.

Review comment:
Yeah, this is exactly what I thought about. You're right. We would need
to pass both the `line` and the start index to `parse`. For the headers' call,
it would be `0` all the time. For the key's call, it would be `offset(headers)`.
This is basically a minor optimization, avoiding to unnecessary allocate a
`String` with `line.substring(offset(headers))` as we could work on `line` all
the time. I don't feel strong about this so I leave it up to you.

Review comment:
* It seems that we supported separator of arbitrary size before whereas
now we always assume 1.
* I am curious about this check: `if (n + keySeparator.size > line.size)
""`. We don't have it anymore with your changes. Do we still need it?
