Why did you rename encrypt to tfheEncrypt?

[immortal-tofu]

Instead of exposing this decrypt function in the instance, I'd prefer you add it in src/tfhe.ts. Functions in tfhe.ts are already usable in node (for example, we're using createTfheKeypair for tests).

Just to make it symmetrical as we have decrypt for the classical one and tfheDecrypt for FHE.

Cool. Should I store the clientKey in the instance and users passing it to these functions in tfhe.ts?

Will open a new PR with a simpler implementation.
