to a sf object.
merge_edit(orig = NULL, edits = NULL, by = c(id = "layerId"))sf with the original or source data to which
deletes should apply
sf with sf data to edit
named vector with the name of the vector representing
the column in orig that we will use to match and the value of
the vector representing the column in edits that we will
use to match. The argument is intended to work like
the *join functions in dplyr. Note, this function
will only use the first name
and first value of the vector for matching.
