enCRAN release
fixed rare overflow error in rztpois where an explicit cast from double to int was used -- now we use safe_double_to_int to avoid overflow; this overflow resulted in a segmentation fault in x86 hardware and in silent failures in AArch64 hardware. This bug should not be relevant for most practical uses of the package.
added new citation for the paper by Trikalinos and Sereda (2024, doi:10.1371/journal.pone.0311311)
Function arguments are now more consistent.
More extensive numerical checks.
Added C++ code for vectorized functions -- for computational speed and memory efficiency.
Renamed functions to start from draw (instead of nhppp_t), draw_zt (instead of ztnhppp_t), and vdraw (instead of ending in _vec())
Initial CRAN submission.
