Remove Nix (#11)

* Remove Nix

Feedback from Roger and others was to go "vanilla" python project.
Therefore remove Nix, Poetry and go back to published versions of
dependencies such as apsw and lief

* updated readme, added api and new tests
* updated readme to reflect removal of Nix
* added new API sql.py to execute sqlelf directly
* added some new tests for the new API
* reworked the cli.py to invoke the new API
* Addressing feedback from Mark
* format

 ## Development
 
-You must have [Nix](https://nixos.org) installed for development.
-
-This package uses [poetry2nix](https://github.com/nix-community/poetry2nix) to easily setup a development environment.
+You may want to install the package in _editable mode_ as well to make development easier
 
 ```console
-❯ nix develop
-$ sqlelf --help
