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 produce 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 run or a vignette chunk evaluated to produce output from data.
