Subject: [PATCH] add solar-pro support
solar-pro introduces block skip connections where blocks are connected
to other, non-sequential blocks with a scale multiple
this change adds 4 new keys to store the skip connections and one new
tensor to store the scalar. the scalar is implemented a 1-dimensional
tensor with 2 elements dervied from the model's bskcn_tv configuration.
in general, the values are (bskcn_tv, 1 - bskcn_tv)
