replace_zeros() throws an error if the input data is a data.frame not a matrix

It's because of the ifelse function.

featuretable/R/feature_table.R

Line 1651 in 083f3f5

new_feature_table <- ifelse(self$data < tol, replacement, self$data)

Need to change it to something that also works with data frames.

Or, need to convert the input into a matrix when calling FeatureTable$new.

One thing that always triggers this is when converting from a tibble going straight into the new method. As of now, user needs to remember to convert it to a matrix manually.
