#14620 Sector model export: limit deck lines to 132 characters

Table keywords such as PVTO and SGOF were rewritten by opm-common as one
unbounded line when saving the deck, exceeding the 132 character line
limit of Eclipse 100 and making exported sector models unusable there.

Update the custom-opm-common submodule so DeckOutput tracks the current
line width and wraps records at item boundaries before a line exceeds
132 characters. Quoted values are never split. Add a regression test
that round-trips a deck with a long rel. perm. table and a record of
quoted mnemonics.
