Add functionality to directly access BBS data?

[diazrenata]

I could add functionality to download and process BBS data through this package. So far I have not done this, in order to keep this package lightweight and focused on the key functionality of estimating size measurements for birds. Adding it might make it easier for users to extract size estimates for populations/communities on specific routes.

The rdataretriever package includes functionality (and a vignette) for loading BBS data; MATSS does as well (using the retriever under the hood). (In fact I have always worked with BBS data downloaded via MATSS.

My thinking is to avoid duplication of effort by reworking the problem of downloading BBS data; but to work through the exercise of downloading BBS using the general-user instructions for the retriever and using birdsize to work with those data; probably including instructions/a vignette for doing so.
