Error details & Generator improvements (#22)

* More error checking/code cleanup

* Create ObjectExistsError

* Read templates from files.

Syntax highlighting on templates if helpful. 😊

* Document how to run the generator

* Template type fixes

* Fix generator (note: only tested with manage schema)

* Improve exception

* Regenerate Manage models with 2022.1 schema

* Have pre-commit reformat line ending change

* Allow model/endpoint generation to run separately.

* Lazy-load endpoints

This resulted in a memory usage reduction from ~240Mb to ~50Mb and a time reduction from 2.8s to 136ms when running `python -c 'import pyconnectwise'`.

* Sort child endpoints so the endpoint files always generate the same.

* Regen manage 2022.1 with sorted child endpoints.
