Consider creating a way to encode and decode candid from Azle

[lastmjs]

It might not be that hard to allow encoding and decoding candid in Azle. See here: https://github.com/dfinity/candid/tree/master/tools/didc

We could hopefully import the didc Rust library and expose an encode and decode function, allowing the developer to pass in a string and get back the hex string or the array of bytes, and the reverse process for decoding.

Would this be useful?

This is related: #263

We might be able to just use the dfinity js agent to encode and decode

Implemented, ic.candid_encode and ic.candid_decode
