Hardware-based support for 'CRC32C' cyclic redundancy checksum function
  is made available for 'x86_64' systems with 'SSE2' support as well as for 'arm64', 
  and detected at build-time via 'cmake' with a software-based fallback.  This
  functionality is exported at the 'C'-language level for use by other packages.
  'CRC32C' is described in 'RFC 3270' at <https://datatracker.ietf.org/doc/html/rfc3720>
  and is based on 'Castagnoli et al' <doi:10.1109/26.231911>.

Different approaches to censored or truncated regression with 
  conditional heteroscedasticity are provided. First, continuous 
  distributions can be used for the (right and/or left censored or truncated)
  response with separate linear predictors for the mean and variance. 
  Second, cumulative link models for ordinal data
  (obtained by interval-censoring continuous data) can be employed for
  heteroscedastic extended logistic regression (HXLR). In the latter type of
  models, the intercepts depend on the thresholds that define the intervals.
  Infrastructure for working with censored or truncated normal, logistic,
  and Student-t distributions, i.e., d/p/q/r functions and distributions3

Frequentist statistical inference for cluster randomised trials with
  multiple outcomes that controls the family-wise error rate and provides nominal
  coverage of confidence sets. A full description of the methods can be found in Watson et al. (2023) <doi:10.1002/sim.9831>.

Provides a new method for interpretable heterogeneous 
    treatment effects characterization in terms of decision rules 
    via an extensive exploration of heterogeneity patterns by an 
    ensemble-of-trees approach, enforcing high stability in the 
    discovery. It relies on a two-stage pseudo-outcome regression, and 
    it is supported by theoretical convergence guarantees. Bargagli-Stoffi,
