LGTM, we are already indirectly depending on dcrec/secp256k1/v4 v.4.0.1 (thats why the go.sum didn't change) and getting rid of the intermediary dependency is good, esp of one that we had issues with in the past wrt. their backwards comp

Use `github.com/decred/dcrd/dcrec/secp256k1/v4` directly rather than `github.com/btcsuite/btcd/btcec/v2` which is just a wrapper around the underlying decred library. Inspired by cosmos/cosmos-sdk#15018 `github.com/btcsuite/btcd/btcec/v2` has a very annoying breaking change when upgrading from `v2.3.3` to `v2.3.4`. The easiest way to workaround this is to just remove the wrapper. Would be very nice if you could backport this to the release branches.
