Sequential circuit

[Nozidoali]

• fix BLIF reader/write BLIF for sequential circuits
• consider sequential logic during cut enumeration and when collapsing mapped network
• close #572

[Nozidoali]

Ready to merge if all tasks below are checked :))

• [x] fix write_blif
• [x] add test cases for write_blif that the previous implementation would fail.
• [x] add test cases for name_viewed BLIF read/write

Thank you for the contribution. A few things:

• Updates to lorina should be made in the source repository first. It would also be great to provide a test case there to justify your fix.
• Changes to network interfaces should be documented.
• Would also be nice to have a test to ensure correctness of sequential cuts.

Todos (ready to merge if all boxes below are checked)

• [x] remove unnecessary modifications
• [x] update changes to the interface in the documentation
• [x] add test cases for sequential k-LUT mapping
