openxlsx2 in webr

[JanMarvin]

To try openxlsx2 without a local installation you can now try it in webr. Visit https://webr.r-wasm.org/latest/ and paste the following

install.packages('openxlsx2', 
  repos = c(
    'https://janmarvin.r-universe.dev',
    'https://cran.r-universe.dev'
))

and paste the contents from our README

library(openxlsx2)
# read xlsx or xlsm files
path <- system.file("extdata/openxlsx2_example.xlsx", package = "openxlsx2")
read_xlsx(path)

You cannot use wb$open() (or at least I couldn't), but you can prepare workbooks and save them, but have to download them to open them in your local computer.

I've added webr to the introduction here. But not sure I like this and might remove it soon.
