document issue: proxyPSK is 32 random bytes in base64?

[busylog]

func NewZeroOverheadHandler(psk []byte) (Handler, error) {
    cb, err := aes.NewCipher(psk)
    if err != nil {
        return nil, err
    }

    aead, err := chacha20poly1305.NewX(psk)
    if err != nil {
        return nil, err
    }

so seems psk is 32 bytes, AES-256 is selected.

simple generator:

python3 -c 'import os,base64; print(base64.b64encode(os.urandom(32)).decode("ascii"))'

You can simply do wg genpsk, or openssl rand -base64 32. No need to use Python.

It's now documented in README.
