encodeAddress method

[iskysun96]

Problem

There is no encodeAddress method that can encode byte32 representation of an account address.

Solution

Replicate the encodeAddress method in JS algosdk: https://github.com/algorand/js-algorand-sdk/blob/ad873ada1f32cbc52519f900e168b71d603ed3bb/src/encoding/address.ts#L103

Is this still relevant?
