8/// Creates a mint redeemer for a Plutus script.
9///
10/// This function encodes a given string label as a hex string, converts it to bytes,
11/// and wraps it into `PlutusData` of type `BoundedBytes`. The result is serialized
12/// as a fragment.
13///
14/// # Arguments
15///
16/// * `label` - A string that represents the label to encode.
17///
18/// # Returns
19///
20/// * `Vec<u8>` - The encoded PlutusData fragment as a byte vector.
21///
22/// # Panics
23///
24/// * If the label cannot be converted into a valid hex string.

33/// Creates a spend redeemer for a Plutus script.
34///
35/// This function takes three hex-encoded strings (`z`, `g_r`, `pkh`), converts them to byte vectors,
36/// and constructs a `PlutusData` structure with a custom `Constr` type (tag `121`).
37/// The resulting data is serialized as a fragment.
38///
39/// # Arguments
40///
41/// * `z` - A hex-encoded string representing the first field.
42/// * `g_r` - A hex-encoded string representing the second field.
43/// * `pkh` - A hex-encoded string representing the third field.
44///
45/// # Returns
46///
47/// * `Vec<u8>` - The encoded PlutusData fragment as a byte vector.
48///
49/// # Panics
50///
51/// * If any input string cannot be converted into a valid hex string.
