Update requestRedemption fn in threshold-ts lib

In the dapp in redemption flow the user needs to provide the BTC address
that the redeemed funds will be locked to but the `requestRedemption` fn
from `tbtc-v2.ts` lib expects the output script. Here we allow to pass
the BTC address to our implementation of the `requestRedemption` fn and
we convert the BTC address into otput script under the hood using the
`createOutputScriptFromAddress` helper function from the `tbtc-v2.ts`
lib.
