Hi, thank you for the nice contribution! I just have one stylistic nit.

This eliminates the unsafe code in this module, and also uses less memory (1 machine word per line rather than 2).
I originally thought I could just store the offsets pointing to the end of the line, but then realized that the string returned by
get_line()doesn't include the line terminator, so I bitpacked the type of line terminator into the index. If that's too overengineered, I could change it to just trim a trailing cr/lf/crlf off the string, but that might entail extra branching in the happy path.
