Huracan

One new component, some improvements, considerably simplified code.

- Added bleed duct component
- Corrected combustion chamber bug where the isentropic efficiency was getting applied twice
- Refactored `engine.py` to simplify the implementation and visualization code
- Added engine and other new tests

This alpha release refactors Huracan to solve https://github.com/alopezrivera/huracan/issues/3.

Changes
- Make it compatible with the most recent version (5.5) of `mpl_plotter`
- Removes the `Python-Alexandria` dependency

Targets for 0.1 release
- Replace plotting methods by single method which takes two strings indicating which parameters to plot against each other (instead of `plot_T_s` etc.)

Plot refinements.

Plotting methods

- Added colorblind support to system plots.

- Updated methods to be compatible with MPL Plotter 4.1.0.

Streams and systems

Set and superset class and constructor metaclass implementation.

Power available bug
Power available calculation division by 0 error at airspeed 0 fixed. The power available and propulsive efficiency now return 0 in such conditions.
