Helper function that calculates excess and population hazards for a given transition

A function that calculates the excess and population hazards for a given transition. Code is based on function rs.surv from the relsurv package.

haz_function(
  formula = formula(data),
  data,
  ratetable = relsurv::slopop,
  na.action,
  add.times,
  rmap,
  include.all.times = FALSE
)

`formula`	A non-parametric Surv-based formula, e.g. Surv(times, status)~1
`data`	A subset of the msprep object (dataset) where there's only data for the chosen transition
`ratetable`	A table of event rates, organized as a ratetable object, such as slopop
`na.action`	A missing-data filter function, applied to the model.frame, after any subset argument has been used. Default is options()$na.action
`add.times`	Additional times at which the hazards should be evaluated
`rmap`	An optional list to be used if the variables are not organized and named in the same way as in the ratetable object
`include.all.times`	Should hazards be evaluated at all times in seq(minimum time, maximum time, by=1). Default is FALSE

A list containing the needed hazards.
