Would an eventual patch supporting importing plaintext accounting file registers be welcome?

[trevorld]

Hi, I currently have an alpha version of a package that can read in the registers from ledger, hledger, and beancount plaintext accounting files as a data frame: https://github.com/trevorld/ledgeR

When the package reaches beta would a patch contributing an .import_beancount, .import_bean, .import_ledger, and .import_hledger to rio be welcome? Each of them would essentially be aliases for ledgeR::register. We'd need to add ledgeR to rio's Suggests field. Additionally in order to actually import the format the user would also need the relevant open-source program installed on their machine of either ledger (>= 3.1), hledger (>= 1.4), or beancount plus hledger (>= 1.4).

Or would it be better to add those import methods to my package and add rio to the Enhances field in my DESCRIPTION?

Given that your package as system dependencies, I wouldn't want to include support directly here. Happy to take a PR here: https://github.com/leeper/rio/blob/master/R/extensions.R to include your package as suggested import tool for those formats, though.
