Subject: [BIP78] Recommended fee rate estimation for P2TR

Non-Witness:

Outpoint size = 32+4
Sequence size = 4
ScriptSig VarInt Size= 1

Witness:

WitScript VarInt Size= 1
Then script itself: 65 signature size + 1 byte of push opcode

`(32 + 4 + 4 + 1) + (65+1+1)/4=57.75`, rounded up `58`.

We assume 65 of signature size rather than 64, since we can't assume the sighash to be `Default`.
