dev-ml/seq: bump to 0.2

This doesn't rely on opam so will break a circular dep:
(dev-ml/seq-1:0/1::gentoo, scheduled) depends on
 (dev-ml/opam-installer-2.0.7-r1:0/2.0.7::gentoo, scheduled) (buildtime)
  (dev-ml/opam-format-2.0.7-r1:0/2.0.7::gentoo, scheduled) (buildtime)
   (dev-ml/re-1.9.0:0/1.9.0::gentoo, scheduled) (buildtime_slot_op)
    (dev-ml/seq-1:0/1::gentoo, scheduled) (buildtime_slot_op)

Package-Manager: Portage-3.0.14, Repoman-3.0.2
