apparently adding nan argument to fcoalesce in #7189 has created a new documentation-related warning in maditr: https://rcdata.nau.edu/genomic-ml/data.table-revdeps/analyze/2025-08-31/maditr.txt

The issue happens because maditr::coalesce was set to data.table::fcoalesce (docs only had entry for ... and not nan), and the fix was to change its definition (using ... to forward all arguments, nan argument does not need to be documented).
