Merge rust-bitcoin/rust-bitcoin#1613: Implement from arrays for `TaprootMerkleBranch`
118a593c89
Implement from arrays for TaprootMerkleBranch (Tobin C. Harding) Pull request description: The `TaprootMerkleBranch` contains a vector of `TapNodeHash`s, as such it can trivially be constructed from an array of the same type. Implement `From` for all array sizes 1 - 128 inclusive. Fix: #1469 ACKs for top commit: Kixunil: ACK118a593c89
