Export plotly::expect_doppelganger

[lcougnaud]

Hi,

First of all, thanks for this great package. I am creating a R package to create custom plotly plots, and would like to include unit tests within this package. In this context, I was wondering if it would be possible to export the expect_doppelganger function included within the package (or the write_plotly_svg function)? That would greatly facilitate the testing of any R visualization package depending on plotly. Thanks in advance!

Up, is there a reason why it's not exported ?
