Function hexStringLayout

Creates a custom binary layout for encoding and decoding hexadecimal strings.

This function provides a structured way to store and retrieve HexString values within binary data layouts, commonly used for binary serialization in Neon EVM transactions.

hexStringLayout(length: number, property?: string): Layout<string>
Parameters
- length: number
  The length (in bytes) of the expected hexadecimal string.
- Optionalproperty: string
  An optional property for the layout.
Returns Layout<string>
A binary layout structure capable of encoding and decoding hex strings.

How It Works
- Encodes hex strings into binary format for efficient storage.
- Decodes binary data back into a prefixed 0x hex string for readability.
- Uses buffer operations to manipulate hex data in a structured format.
Example Usage
```
const layout = hexStringLayout(32, "publicKey");
const buffer = Buffer.alloc(32);
layout.encode("0xabcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890", buffer, 0);
const decodedHex = layout.decode(buffer, 0);
console.log(decodedHex); // Outputs: "0xabcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890"
```
