<p>Convert a single polynom back to a real string which is base64 encoded. The polynomial coefficients are expected to be in the range [0, q-1] and will be casted back to chars without any mapping.</p>
<p>Trailing q coefficients are only used for filling up the rest of a polynomial with '\0', so they will not confuse the result.</p>
