In linelist: Tagging and Validating Epidemiological Data

# This helper ensures the package does not modify the session global state. As
# per CRAN policy, packages should not interfere with the user's session state.
# If global settings need to be modified, they should be restored to their
# original values on exit. This can be achieved with the `on.exit()` base
# function, or more conveniently with the `withr` package.
