- The delta offset and flags combined may be larger than u64,
so handle the first byte separately.
- Use wrapping arithmetic.
- Change `Crel::r_sym` and `Crel::r_type` to u32.
- Add `Crel::symbol()`.
- Fuse `CrelIterator` on error.
- Replace `ElfRelaIterator` with `ElfRelocationIterator` which returns
`Crel`. This avoid the need to byteswap the `Crel`, and thus avoids
the use of `Endian::default` (which may not match the file).
- Add test outputs.
