adheaping 1.0.0

• Initial release. Characteristic-function de-heaping density estimation for heaped and rounded data:
  • tuning-free box-deconvolution de-heaping estimator (deheap_kde), superposition (superpose_kde), and the combined band-capacity-gated estimator (adkde);
  • blind grid, heaped-fraction, and mixed-grain (subgroup-lattice) readers (heap_grid, heap_fraction, heap_lattice);
  • a spectral higher-order comb detector (heap_detect);
  • faithful base-R replicas of measurement-error deconvolution (deconv_kde) and the Heitjan-Rubin multiple-imputation approach (heitjan_mi), and a wrapper for the Kernelheaping stochastic-EM estimator (sem_kde). Derived from the spectral-decomposition kernel density estimation of Thornton (arXiv:2606.15450).
