Merge rust-bitcoin/rust-bitcoin#4648: units: Test generic `Add` and `Sub` 

a520a8ab08 units: Test generic Add and Sub (Tobin C. Harding)

Pull request description:

  We have `Add` and `Sub` implemented for `NumOpResult<T>` but because the impls are generic they are not grouped in the file with the other add/sub impls. This makes it hard to see if they are supported.
  
  Add to the `add` and `sub` unit tests to verify support is implemented.
