convert 0x to f4 programmatically

[trruckerfling]

Firstly, clarification that f4 addresses are separate from f1, f2 and f3 addresses. More here.

You can programmatically convert 0x addresses to f4 addresses by using filecoin.solidity library here

For the client side you can use this library. Example:

const filecoin = require("@glif/filecoin-address");
const f4Address = filecoin.newDelegatedEthAddress(deployer.address).toString();
