Description: Functions to design and apply tests that are anytime valid. The
  functions can be used to design hypothesis tests in the prospective/randomised
  control trial setting or in the observational/retrospective setting. The
  resulting tests remain valid under both optional stopping and optional
  continuation. The current version includes safe t-tests and safe tests of
  two proportions. For details on the theory of safe tests, see Ly, A, Boehm, 
  Grunwald, Ramdas and van Ravenzwaaij (2024). "Safe Anytime-Valid Inference: 
  Practical maximally flexible sampling designs for experiments based on e-values" 
  (<doi:10.31234/osf.io/h5vae>) and Grunwald, de Heide 
  and Koolen (2024) "Safe Testing" (<doi:10.1093/jrsssb/qkae011>), for details 
  on safe logrank tests see ter Schure, Perez-Ortiz, Ly and Grunwald (2024) 
  "The Anytime-Valid Logrank Test: Error Control under Continuous Monitoring with 
  Unlimited Horizon" (<doi:10.51387/24-NEJSDS65>), and Turner, Ly and 
  Grunwald (2024) "Generic E-variables for exact sequential k-sample tests that 
  allow for optional stopping" (<doi:10.1016/j.jspi.2023.106116>) for 
  details on safe contingency table tests.
