build_gs_bern()
builds a multi-stage group-sequential multi-arm
clinical trial design object assuming the primary outcome variable is
Bernoulli distributed, like those returned by des_gs_bern
.

n10 = 77,
n1 = n10 * (1 + K * ratio),
e = c(2.42, 2.42),
f = c(-2.42, 2.42),
K = 2,
alpha = 0.025,
beta = 0.1,
pi0 = 0.3,
delta1 = 0.2,
delta0 = 0,
ratio = 1,
power = "marginal",
stopping = "simultaneous",
type = "variable",
spacing = (1:length(e))/length(e),
summary = FALSE

A list
, with additional class
"multiarm_des_gs_bern"
, containing the following elements:
A tibble
in the slot $opchar
summarising the
operating characteristics of the identified design.
A tibble
in the slot $pmf_N
summarising the
probability mass function of the random required sample size under key
scenarios.
A numeric
in the slot $maxN
specifying
max N, the trial's maximum required
sample size.
A numeric
in the slot $n_factor
, for internal use
in other functions.
Each of the input variables.
