Adds a new `ewf` crate with EWF1/EWF2 readers and writers, LEF read support, and a delta overlay. The `ntfs` image backend now wraps `ewf::EwfReader` while preserving the existing `EwfImage` API. Pins the libewf reference commit (without vendoring a full snapshot) for parity work.

Use the bounded section data length to avoid over-reading malformed sections, and add a regression test that corrupts the descriptor-reported size.
Reject bp=0/sb=0 early to prevent chunk_size=0 division-by-zero panics, and add regression tests for Ex01/Lx01.
Document supported AFFLIBv3 behaviors and pin upstream reference commits for parity work.
