It appears there is no way to access the raw ELF file contents when using `ElfStream`. In my particular case, I want to iterate the segments, and then read that segment data. * None of the [`ElfStream` methods](https://docs.rs/elf/latest/elf/struct.ElfStream.html#implementations) allow this. There is no `segment_data()` (only `segment_data_as_notes()`). * There is no accessor to borrow the `.reader` Is there a workaround I'm missing? Is there a reason `segment_data()` doesn't exist? Would you support the addition of this?
