docstr: Maps raw tensors to valid arguments for constructing a ZeroInflatedBeta
  distribution.
  
  Parameters
  ----------
  F:
  alpha:
      Tensor of shape `(*batch_shape, 1)`
  beta:
      Tensor of shape `(*batch_shape, 1)`
  zero_probability:
      Tensor of shape `(*batch_shape, 1)`
  
  Returns
  -------
  Tuple[Tensor, Tensor, Tensor]:
      Three squeezed tensors, of shape `(*batch_shape)`: First two have
      entries mapped to the positive orthant, last is mapped to (0,1)
