Dynamic Codegen in Rust with Daedalus (#67)

* Added libs/cangen, to move the CAN types and some of the CAN codegen logic into Calypso from Embedded-Base

* Added libs/daedalus, which exports proc macros to generate decode, encode, and simulate functions and mappings at compile time

* Changed main to work with new code generated by daedalus macros

format_data.rs is no longer generated, FormatData struct now hardcoded into data.rs

Removed deprecated exports from lib.rs

Removed calypsogen.py and its call in build.rs

Changed Cargo.toml/.lock to include new dependencies (phf, cangen, daedalus)

Removed deprecated files from .gitignore

Now tracking decode_/encode_/simulate_data.rs, as they contain macro calls

* Fixed bugs, now building and working

* Implemented PR changes, refactored calypso-cangen traits for readability

* Fixed for clippy

* Allow clippy

* Begrudging clippy compliance

* Bug fix for reading small little endian values
