This commit extends Opm::data::Wells to include a set of output vectors for well segment information. At present we define output structures for segment rates and segment pressures. The immediate use case is properly assigning restart vector items RSEG[8 .. 11], but these same values are also usable for outputting the summary vectors SPR, SOFR, SGFR, and SWFR. Future expansion is likely.
