Working star coloring

[gdalle]

Source

• Re-export and document column_coloring, row_coloring and symmetric_coloring from ADTypes
• Remove star_coloring1, which was a naive algorithm from 2005
• Implement star_coloring, a better algorithm from 2007
• Remove check_structurally_orthogonal_rows since it is achievable with check_structurally_orthogonal_columns by transposition, rename check_symmetrically_orthogonal to check_symmetrically_orthogonal_columns
• Add size checks and improve the log messages in both remaining checks
• Rename colors to color and groups to group everywhere to be more coherent with the papers
• Rename C into B for decompression to be more coherent with the papers
• Slightly more efficient symmetric recovery algorithm

Tests

• Add more tests on the checks, including the log messages
• Remove comparison to the naive star coloring since it has disappeared

Docs

• Add more sources to the README and docstrings
