v0.3.2

• powerio-dist OpenDSS: grounding reactors written from a bus terminal to the
  same bus's node 0 now type as shunts in BMOPF instead of staying untyped.
  Impedance form reactors use the equivalent admittance matrix, so neutral
  grounding resistors survive DSS to BMOPF conversion.
• powerio-dist OpenDSS: delta capacitor and reactor banks now type as shunt
  admittance matrices, including off diagonal branch terms, instead of being
  dropped as untyped objects.
• DSS writing now regenerates conductance bearing shunts as grounding reactors
  and preserves delta shunts as conn=delta where the typed model identifies
  them.
• No core or distribution C ABI break; PIO_ABI_VERSION stays 4 and
  PIO_DIST_ABI_VERSION stays 1.

What's Changed

• Fix DSS shunts in BMOPF conversion by @samtalki in #140
