Removed usages of deprecated fields

[kamikaz1k]

(preface) Hi o/ not sure if you're looking for PRs in this category of work but I saw #571 and it was annoying me in my builds, so I thought I would try to solve it instead of piling on. That being said, I did a very naive refactor based on what I understood. Ya'll might have had more comprehensive plans about how you wanted to arrange things. But hopefully this is roughly in the ballpark. (/preface)

There were a number of deprecation errors being emitted from the package, so I have attempted to update all those references by essentially taking the wrapping code and moving it closer to the calling site. I did my best with the understanding of the interactions.

I have also added a Makefile that makes is easier to set up a dev environment and get tests running. I realize I am imposing this, so let me know if you would rather not have this.

Makefile output:

$ make

$ make env

$ make test

+1 from me to get this or a similar fix merged.

This greatly reduces the number of deprecation warning I see in my schematics project. (Still have one call to deprecated function fields, from deprecated.py line 65.)

Is there a maintainer who can review, merge and release a 2.1.1 if this is okay?
