Function multibaseIdToKeyBytes

multibaseIdToKeyBytes(params): Required<KeyWithMulticodec>
Converts a multibase identifier to a cryptographic key.
Parameters
- params: {
  multibaseKeyId: string;
  }
  The parameters for the conversion.
  - multibaseKeyId: string
    The multibase identifier string of the key.
Returns Required<KeyWithMulticodec>
An object containing the key as a Uint8Array and its multicodec code and name.
Remarks
This function decodes a multibase identifier back into a cryptographic key. It first decodes the identifier from multibase format into Base58 format, and then converts it into a Uint8Array. Afterward, it removes the multicodec prefix, extracting the raw key data along with the multicodec code and name.

Example
```
const multibaseKeyId = '...'; // Multibase identifier of the key
const { key, multicodecCode, multicodecName } = multibaseIdToKey({ multibaseKeyId });
```
Throws
DidError if the multibase identifier is invalid.
