Output field updates: Well depth, non-vertical sections, transmission, annualized capex [3.7.0]

[softwareengineerprogrammer]

1. Rename Well depth (or total length, if not vertical) to Well depth per Laterals/horizontals/non-vertical sections not reflected in "Well depth (or total length, if not vertical)" #321. This update is the motivation for the minor version bump from 3.6 to 3.7, since renaming this field is technically a backwards-incompatible change. I considered avoiding introducing backwards-incompatibility, but ultimately landed on the minor version bump for the following reasons:
   1. The previous field name - Well depth (or total length, if not vertical) - was inaccurate and actively misleading. The actual value was always just the well depth and never total length, even if not vertical.
   2. The field was/is also redundant with the Reservoir Depth input. Thus it's less likely that anyone programmatically consuming the client results would be consuming this field specifically, lessening impact of the backwards-incompatible change.
2. Fix non-vertical drilling costs field parsing
3. Add missing capex fields to client result: Transmission pipeline cost, Annualized capital costs

TODO: in documentation, add note on Output parameter indicating "Well depth" = "Vertical depth"/TVD

Looks good to me.
