Describe the bug/issue

The library call to load the flepicommon package is quite verbose and indicates some issues with how the dependencies are setup for that package.

1. The packages dplyr and magrittr should be moved from depends to imports to avoid attaching those packages.
2. Explicitly import when and accumulate from purrr over foreach to get rid of the conflicting imports warning message.

To Reproduce

> library(flepicommon)
Loading required package: dplyr

Attaching package: ‘dplyr’

The following objects are masked from ‘package:stats’:

    filter, lag

The following objects are masked from ‘package:base’:

    intersect, setdiff, setequal, union

Loading required package: magrittr
Warning messages:
1: replacing previous import ‘foreach::when’ by ‘purrr::when’ when loading ‘flepicommon’
2: replacing previous import ‘foreach::accumulate’ by ‘purrr::accumulate’ when loading ‘flepicommon’

Environment, if relevant
