Ability to download shapefiles for assessment areas

[WMRobin]

Is your feature request related to a problem? Please describe.
Not a problem per se, but I would like to be able to map the stocks in this dataset using shapefiles. The stocks are described as a couplet of species and area.

For example,

get_species_itis(stock = "Atlantic cod")
#> # A tibble: 3 × 3
#>   StockName                           Jurisdiction   ITIS
#>   <chr>                               <chr>         <dbl>
#> 1 Atlantic cod - Eastern Georges Bank NEFMC        164712
#> 2 Atlantic cod - Georges Bank         NEFMC        164712
#> 3 Atlantic cod - Gulf of Maine        NEFMC        164712

tells us there are three stocks of Atlantic cod. I have an idea of where the Eastern Georges Bank is, but I would like to have a formal shapefile to outline it.

Describe the solution you'd like
An ideal solution would be to have some function, say stocksmart::get_shape(location = "Eastern Georges Bank"), that downloads a SimpleFeatures or other Shape object in R for the requested location's shapefile.

But, a completely sufficient solution would be to just provide a link the shapefiles in this repo's ReadMe file.

Additional context
I am conducting a study in which I need to link recreational catch data from MRIP to fish stocks.
