Update to follow rlf and other fixes

[alihamdan]

Copy changes made in rlf, fixes, and enhancements.

Fixes:

• Fix wrong transformer parameters when updating tap or parameters. It was using the wrong z2, ym and k
• Fix network frames missing newely added fields like nominal_voltage, loading, etc in addition to missing tap for transformers
• Fix voltage_level not set for en.res_buses if voltage limits are not defined but nominal voltage is defined
• Add missing full results such as voltage_level for buses, loading for lines and transformers
• Add missing line_type setter on line parameters similar to material and insulator
• Fix slow res_violated for transformers using the same trick used for lines earlier
• Fix links in docstring to point to rlfs classes instead of rlf classes
• Fix type annotations to use broad types for inputs (union defined aliases like Float) and narrower types for outputs (like float). Add missing | Q_[] in some places.

Enhancements:

• Add top-level types module from rlf
• Add SQRT3 constant from rlf
• Use faster coverage in CI
• Copy improved error messages from rlf for the case of a singular matrix
• Improve tests of electrical network
• Use precise typing for cy elements
