Droid-metapatch

Added
- Circuits have their memory consumption stored. This could allow for analysis to be added later.

Changed
- The transform function `input` and `output` parameters have been renamed to
`new_input` and `new_output`. This may break your code if you use that
function! The `add_circuits()` instance function has not been changed.

- The circuit.json parsing has been refactored and greatly improved.

Fixed
- Fixed a bug with processing empty circuits
- Fixed a bug that would make booleans always return True

Changed
- Updated and improved documentation and other metadata.

This is a major overhaul that adds support for native Droid circuits, overhauls and completely changes the CLI utility and much more.

Changed
- If no presets have been defined, a default preset will be created.

Added
- Added a small helper script that can convert droid patches to python code. This script is added as `droid-metapatch`.
