Decodes one packed param back to something sql.exec() can bind.
$b64 is bytes that were not valid UTF-8. $i is an integer outside the IEEE-754
safe range: it is bound as a decimal STRING, because SQLite's INTEGER
affinity converts a well-formed integer string losslessly on the way in, while a JS
number would already have lost the low bits before the binding saw it.
