**Full Changelog**: https://github.com/opusonesolutions/carsons/compare/0.5.0...1.0.0

Sequence Impedances can be calculated from phase-impedance matrix using the formula `z₀₁₂ = Aₛ⁻¹ ⋅ z_abc ⋅ Aₛ`. This release adds `calculate_sequence_impedance_matrix` which implements this formula, as well as `calculate_sequence_impedances` which reduces the impedance to a balanced `z1`, `z0` pair. H/T to bluejuniper for the implementation

Refactors the MultiConductor model inputs to specify `outsideRadius` and not `radius`/`insulation_thickness`. This disambiguates `radius`, which could be interpreted by some as the radius of the inner conductor, or some other radius.

carsons` now support modelling of multi-conductor cables, such as duplex, triplex, quadruplex and triplex secondary.

Adds type-hinting to improve the readibility of `carsons`; also adds a `py.typed` file to support using `mypy` on code that depends on `carsons`.
