The problem with a read/seek interface is that you are consuming a
resource (a memory window) while you are using it.  You'd need an
open/close on top of that as well to properly map things in to start
and then free them at the end.  Plus you might want a ftell sort of
interface as well.  I'll likely punt on the seek/ftell part.

But it would make the client code a little easier to cope with:

        uchar8_t cis[CIS_MAX_LENGTH];
        size_t len;
        cis_cookie_t cookie;

        card_map_cis(dev, &cookie);
        while (card_read_cis(dev, cookie, cis, &len)) {
                frob the cis entry
        card_unmap_cis(dev, cookie);

I'll see how hard it would be to come up with this, if this sort of
interface is reasonable.
