Prepare for CRAN release

[Bisaloo]

I have not reviewed the package code or design but upon a cursory look, here are the points that almost surely will cause issues with CRAN:

• [x] the package is too large (>= 5MB):
  • some data is duplicated across data and inst/extdata, can this be fixed?
  • can a subset of the dengue2020 dataset be used in examples? Examples are just here to demonstrate the function usage, it's not so important if the result is not necessarily meaningful from a scientific point of view. Vignettes are here to fill this gap.
  • the getting_started.Rmd and sivirep.Rmd vignettes seem mostly duplicated (both leading to an almost 50MB HTML file)
  • I would convert the gif to webm, which is widely supported by all web browsers now (source): I achieved a 20x file size reduction doing this (with ffmpeg). Please let me know if you'd like me to submit a PR with this change
• [x] examples take too long
  • this should be improved automatically if you follow the smaller example dataset recommendation above
  • longer examples should be wrapped in \donttest{}
• [x] the package is in Spanish. This is not a problem in itself but it's uncommon enough that CRAN is likely to raise an eyebrow over this. I would pre-empt any comments by explaining in cran-comments.md to scope of the package, why it has to be in Spanish, and how you have tried to follow recommendation from the official 'Writing R Extensions' guide: https://cran.r-project.org/doc/manuals/R-exts.html#The-DESCRIPTION-file-1

Hi @Bisaloo, thanks for your review 😊:

• the package is too large (>= 5MB):
  • I'm currently working on reducing the size of dengue2020. I've addressed this in issue #133, but I've also created a separate issue #150 to highlight this concern for reviewers' convenience.
  • Yes, it's possible to remove the duplicated data.
  • Please proceed with the PR for converting to webm.
  • I'll check the vignettes.
• examples take too long:
  • I've wrapped some longer examples in\dontrun{}. I'll evaluate which functions to implement \donttest{} and replace \dontrun{}.
• Thank you for bringing up this point. We'll provided a detailed explanation of the package's scope and why Spanish is necessary for its users and NIH needs.

Hi @Bisaloo,

The issue related to the size of the dengue2020 dataset was resolved in PR #167; now its weight is 4.3 KB
