dataset_fill_value_in now takes the file as any Storage (generic, so every &[u8] caller compiles unchanged) and follows a shared fill value message through message_data_with_sohm_in. The raw-data helpers in the module (read_full_with_fill, apply_to_unallocated_chunks) walk chunk indexes and stay on &[u8] until milestone M2. New test: the four datasets of shared_fill_value.h5, two with their fill value in the SOHM heap, resolve identically through a read_at-only CountingStorage.
