feat: merge rpptx objects #718
Description
Feature
The author of this stackoverflow question asked for a way to merge presentations, i.e. rpptx objects. I also had a few times, where this would have been handy.
In some cases, the implementation may not be that easy, for example, if presentations have different master layouts. This may be tricky, but I think we would not need to cover all edge cases.
@davidgohel If you agree, I could implement this ( I already started).
Example
p1 <- read_pptx()
p1 <- add_slide(p1, layout = "Title Slide", ctrTitle = "Presentation 1")
p2 <- read_pptx()
p2 <- add_slide(p2, layout = "Title and Content", title = "Presentation 2")
p3 <- read_pptx()
p3 <- add_slide(p3, layout = "Two Content", title = "Presentation 3")
# concatenate
pp <- pptx_concat(p1, p2, p3)
# same using c()
pp <- c(p1, p2, p3)
