calculate an abridged life table that is consistent with a life table by single year of age

Source: R/lt_regroup_age.R

Computes abridged life table columns based on the lx, nLx , and ex values from a single year life table, in accordance with step 2.2 of the Human Life Table Protocol https://www.lifetable.de/methodology.pdf. Output abridged life table has same open age group as input single age life table

lt_single2abridged(lx, nLx, ex, Age = 1:length(lx) - 1, ...)
