How to port the functions?

• This InCHI API manual can help in determining the function signature: InChI_API_Reference.pdf
• The input/output types of the function signatures are already ported.
• Simply functions need to be ported now. This tutorial can teach you all that is needed.
• These ported functions reside in ffis.ts.
• Wrap the functions such that end users don't need to worry about ref/ref-napi and expose them via src/api.ts.
• Add appropriate unit tests in ffis.test.ts and api.test.ts.
• Expose src/api.ts functions via server.ts as well. (Via Expose all functions in api.ts via server.ts also #26)
• Add JSDOc comments for the functions added to src/api.ts to showcase how to use them. (Via Add JSDoc comments for all api.ts functions to showcase their example usage #27)
