8d8edd2c77 make Debug representation of Witness to be slice of hex-encoded bytes strings (Erick Cestari)
Pull request description:
This PR updates the Debug implementation for the Witness type to improve its readability by displaying the witness data as a slice of hex-encoded strings rather than a concatenated blob or list of raw u8 values. The changes include:
- Improved Output:
The debug output now shows pseudo-fields such as the number of elements and the total length of all elements, making it easier to understand the underlying data without exposing internal indices like indices_start.
- Hex-Encoding:
Each witness element is displayed as a hex-encoded string, similar to Bitcoin Core's output style, which enhances clarity during debugging sessions.
These changes should provide a more developer-friendly view of the witness data and align with similar patterns used elsewhere in the ecosystem.
Closes#4023.
Example display:
```
Witness {
num_elements: 3,
total_bytes: 5,
elements: [
0b,
1516,
1f20,
],
}
```
```
Witness { num_elements: 3, total_bytes: 5, elements: [0b, 1516, 1f20] }
```
