Add vipstar to test vectors and source code

[ROZ-MOFUMOFU-ME]

This pull request introduces the VIPSTAR hashing algorithm to the project. The changes include adding the necessary source files, updating the build configuration, and integrating the new algorithm into existing modules and test vectors.

Integration of VIPSTAR hashing algorithm:

• Added vipstar.c and vipstar.h source files, which implement the VIPSTAR hashing function. (src/vipstar.c, src/vipstar.h) [1] [2]
• Updated binding.gyp to include src/vipstar.c in the build process. (binding.gyp)
• Modified src/multihashing.cc to include and use vipstar.h, and added the DECLARE_FUNC(vipstar) function. (src/multihashing.cc) [1] [2] [3] [4]

Build and configuration updates:

• Updated .vscode/settings.json to include new header files for C/C++ language association. (.vscode/settings.json)
• Adjusted include paths in yespower-opt.c to ensure proper file referencing. (src/crypto/yespower/yespower-opt.c)

Test updates:

• Added VIPSTAR to the test vectors in various JSON files to ensure comprehensive testing coverage. (tests/vectors/set1-input.json, tests/vectors/set1.json, tests/vectors/set2-input.json, tests/vectors/set2.json, tests/vectors/set3-input.json, tests/vectors/set3.json) [1] [2] [3] [4] [5] [6]
