v0.5.1

Logic is 30% faster with the same results, and the repository has its intended name. Nothing in the output or the API changes.

• Repository renamed to albertlast/abapParser, from abapPaser; GitHub forwards the old address. The package links point to the new name.
• Faster logic: the inputs of an effect were traced from each statement writing it anew; the statements now share what was already traced. Logic over the corpus takes 30% less time than in 0.5.0, the logic of whole objects 21% less; the results are the same.
• Benchmark: cargo run --release -p abap-analysis --example bench times each stage over the corpus, node tools/bench.mjs v0.5.0 . compares versions; the README has the times since 0.3.0.
