I'm having second thoughts about the `ChunkReader` interface. It has a
length, but what we really want is the capability to "read from end" in order
to get the parquet footer. So I'm thinking about removing the Length trait and
give to `get_read` the capability to read from end, for instance by making
`start: u64` an `enum { FromStart(u64), FromEnd }`. This is particularly
interesting when reading from a remote store where getting the size is
expensive. What do you think ?
