Notes for pkg check

Several notes about this package :

• devtools::check() return a note about usage of :::, not critical during development.
• strava_activities should be replaced with a data for this package. Ideally in a inst/create_data.R script that use usethis::use_data() so it can be updated later.
• stopifnot(e %in% v) for arguments can be replaced with a match.arg() where all possibilities are placed in argument definition, the first one being default. Example :

#' @param Sport type, multiple choices available, default is "all".
foo <- function(sport = c("all", "run")){
   match.arg(sport)
   print(sport)
}

• get_strava() can use @inheritParams create_strava, to simplify documentation 😁

Everything else is really clean, I'll start to play with it and test if forgemia allows to run dowloads on tanguy with CI/CD tools.
