Dynamic list of unsupported geoms

Here's a list of official ggplot2 geoms that we don't currently support. For a list of 3rd party geoms, see #566

library(plotly)
  # obtain ggplot2's geoms
gg <- ls(asNamespace("ggplot2")) 
geoms <- gg[grepl("^Geom", gg)]
# plotly geoms
x <- sub("to_basic\\.", "", as.character(methods(to_basic)))
y <- sub("geom2trace\\.", "", as.character(methods(geom2trace)))
# non official mechanism for layout-specific geoms yet
pgeoms <- c(x, y, "GeomRasterAnn")
setdiff(geoms, pgeoms)

"GeomCurve"     "GeomCustomAnn" "GeomLabel"     "GeomLogticks"

packageVersion("plotly")
[1]  ‘4.5.6.9000’

重新运行 issue 中的 R 代码片段，并检查其中提到的 to_basic 和 geom2trace 方法列表。与维护者确认目标是支持列出的四个 geom，还是动态报告不受支持的 geom。完成标准应是行为已达成一致，并且列出的 geom 按预期得到处理或报告。
