In bomeara/flipped: Applies various odd models for coin flipping

Compute probability of observations given an exponential decay model

d_coin_multiplicative(
  nheads,
  nflips,
  multiplier,
  log = FALSE,
  possibilities = get_possibilities(nheads, nflips),
  outside_bounds_is_NA = FALSE
)

`nheads`	Number of heads
`nflips`	Total number of flips (heads and tails)
`multiplier`	How much to multiply by each flip
`log`	If TRUE return log transformed probabilities.
`possibilities`	All possible sequences of flips that lead to the observed number of heads
`outside_bounds_is_NA`	If TRUE, if any probability of heads is outside the bounds of probability, the function returns NA. Otherwise, it sets the value to the nearer bound.
