WIP - Add log10 variant adding 1 to every input values in case any zeros are found

We already had a variant (which is still there, but probably it should be removed) that changed zeros into ones before attempting to perform the log10 transformation. It only modifies zeros, keeping the other values unchanged.
The new variant, when any zeros are found in the input, increments all input values by one, instead of just the zeros. As soon as Chris confirms that the latter is the desired behavior, I will remove the old variant.
