tidytacos v1.0.2, function add_alphas() removes samples that have observed equal to 0

Starting from tidytacos v1.0.2, function add_alphas() removes samples that have observed equal to 0, simply printing a warning about it, which is very easy to overlook. See pull request from the tidytacos developers, under the first bullet point ("empty sample checks") and the change in their code.
There is no way to switch this new behaviour off, it will always perform the remove step.
