Availability of geometries from 2006-2009

[LayanKaushik]

Hi, thank you for your fantastic R and Python packages. I noticed that the TIGER/Line Shapefiles are available from 2006 to the present, but tigris and pygris don't include the years from 2006 to 2009. I'm curious to know if there's a specific reason for this, or if it's in your development pipeline. I'd love to understand the reasoning behind it and am open to contributing if possible.

Those shapefiles have a different URL structure than the shapefiles 2011 and later, so they'd take some custom development to support them given the current infrastructure of the packages. I'm happy to review a pull request if anyone would like them added!

Thank you for this package. I'd like to request geometries for years 2008 to 2012
