Detect whether the current deepSTRAPP installation corresponds to
a development version (e.g., version sourced from GitHub), as opposed to a CRAN release.
The development versions include deepSTRAPP outputs as additional internal datasets to help
produces examples and vignettes outputs. These additional datasets are removed from the CRAN releases
because their size is not compatible with CRAN policies.
This function is only used to check if an example must be ran or a vignette chunk evaluated
to produce output from data.
