General purpose CPI not supported #9
Description
As mentioned in https://github.com/Turbin3/poseidon/blob/master/docs/src/mapping-into-anchor/cpi.md, only certain functions from TokenProgram and SystemProgram are allowed as valid CPI calls with Poseidon as of now. This means we can't use CPI calls for any other third party program, severely limiting functionality.
This issue is blocking TypeScript program updates for solana-developers/program-examples
