StyleProvider to highlight overloaded lines in SLD

[So-Fras]

Describe the current behavior

In network-area-diagram, branches and tie lines are set to blink when they are overloaded (i.e. when the current permanent limit is violated).

In single-line-diagram, such a feature does not exist.

Describe the expected behavior

Tie lines, transformer legs, lines, dangling lines that whose current permanent limit is violated should be highlighted with a blinking design supported by a new StyleProvider.

Describe the motivation

This piece of information is also useful in single-line-diagram
