Giving RunDFA a fresh coat of paint

[alxmrs]

• Refactored to use Clikt
• Added a binary argument that will not run tools/sigh manifest2proto, and instead treat inputs as proto binaries
• BUILD file uses standard java_binary instead of java_test.
• Added license.

New usages:

./bazel-bin/java/arcs/tools/run_dfa src/okCheckTests.binarypb -b

SIGH_CMD=./tools/sigh ./bazel-bin/java/arcs/tools/run_dfa javatests/arcs/core/analysis/testdata/ok_check_multiple_or_tags.arcs
