discord 1.2.3.1

Added a new vignette demonstrating the use of the potter dataset from the BGmisc package to create and use other kinship links.
Copy edited existing vignettes

Fixed error when prepping discordant data as a result of mismatched column names between user-supplied data and internally manipulated data. See commit fc1ed9f for more details.
Fixed error where discord_data() returned multiple rows per kin-pair when the ‘id’ column had non-unique values. As a result, the new default for ‘id’ is NULL. See commit 87d5b3b6 for more details.

Added error message for missing data passed to discord_data() for more easy debugging.

Added unit tests ensuring regression results are consistent under multiple conditions (e.g., with and without sex & race arguments)
Removed dplyr, rlang, purrr, magrittr, janitor, and broom dependencies

Added a NEWS.md file to track changes to the package.
Combined the functions kinsim1 and kinsim_multi into kinsim to simplify simulations.
Revised discord_data and discord_regression to support functional programming and the tidyverse principles.
