Please be as descriptive as possible, including what is expected, why is this feature needed, what is the objective, etc.

What is the feature being requested?

1. In the default_options of the TransmonCrossFL, add a type of flux line style.
2. Add a style for MIT's Lincon Labs which allows us to accommodate

What are use cases for this feature?

A lot of researchers send their designs to MIT's Lincon Labs for fabrication. Having this geometry baked into Qiskit Metal should speed up the design + fabrication process!
