readtext::readtext() fails if package has not been loaded

This is because zzz.R has not run .onload() yet to set the options.

Update: this bug still exists in the new release. To reproduce run in a clean R session:

DATA_DIR <- system.file("extdata", "pdf", "UDHR", package = "readtext")
readtext::readtext(sort(list.files(DATA_DIR, full.names = TRUE, pattern = "\\.pdf$")))

@jeroen Thanks for the feedback. Should be fixed when a PR is accepted.

[kbenoit]

It’s fixed now, and I added a more comprehensive approach that allows more options to be added. It works in the same as as quanteda::quanteda_options(), which can be set in .Rprofile for instance but will always be initialized if called without the package being attached.

Will re-submit to CRAN asap.
