Deprecation Warning from tibble 2.0.0

[hannahlowens]

When using bib2df (version 1.1.1) bib2df:::bib2df_gather(bib = myBib) I get the following warning:

Warning (test-occCitePrint.R:19:3): regular print
as_data_frame() was deprecated in tibble 2.0.0.
Please use as_tibble() instead.
The signature and semantics have changed, see ?as_tibble.
This warning is displayed once every 8 hours.
Call lifecycle::last_lifecycle_warnings() to see where this warning was generated.

It looks like this could be fixed by replacing dat <- as_data_frame(dat) with dat <- as_tibble(dat).

Duplicates #48?

Seems to be fixed in development version that can be installed with devtools::install_github("ropensci/bib2df")

@giabaio can we please have a new version released on CRAN? This fix is really helpful as it quiets annoying warnings.

Please and thank you
