Should the txp_example_model object reference the DBI namespace?

I don't know the "right" solution here, but a similar problem has been
discussed here in R-pkg-devel some time ago:
https://stat.ethz.ch/pipermail/r-package-devel/2022q1/007633.html

You might have to depend on DBI explicitly because your data() object
uses it, but then `R CMD check` might object that you don't explicitly
import anything from it. One admittedly verbose way to work around that
would be to move the data file to inst/ and load it from
data/txp_example_model.R only after loadNamespace('DBI'), like some
data scripts do in the Matrix package.
