Feature: Supports enumerating Ed25519 and P521 credentials within FIDO

[DennisDyallo]

This pull request includes adds support for Ed25519 FIDO credentials and updates to the EcdsaVerify class within the Yubico.YubiKey.Cryptography namespace to enhance its flexibility and maintainability. The changes primarily focus on extending the supported elliptic curves, refactoring the code for better readability, and improving error handling.

Will also fix this: virot/powershellYK#86

Key updates include:

Support for Additional Curves

• CoseEdDsaPublicKey adds support for enumerating Ed25519 credentials
• Extended support to include P-521 curve, in addition to existing P-256 and P-384. Updated relevant methods and comments to reflect this change. [1] [2]

Refactoring and Code Simplification

• Introduced GetOidByAlgorithm and GetOidByLength methods to streamline the process of obtaining OIDs based on algorithm identifiers and encoded point lengths, respectively. [1] [2]
• Removed hardcoded constants for key sizes and OIDs, replacing them with dynamic calculations and lookups from KeyDefinitions. [1] [2]

Error Handling Improvements

• Enhanced error handling by adding more specific exception messages and conditions, ensuring that unsupported algorithms are correctly identified and reported. [1] [2]

Documentation Updates

• Updated method documentation to accurately describe the extended curve support and the changes in signature verification processes. [1] [2] [3]

Code Cleanup

• Removed redundant comments and unnecessary private constants to clean up the codebase and improve readability. [1] [2] [3] [4]

These changes collectively enhance the functionality and maintainability of the EcdsaVerify class, ensuring it can handle a wider range of elliptic curve signatures with improved clarity and robustness.

Some minor things, also add tests on CoseEdDsaPublicKey

[DennisDyallo]

Just have one question regarding the Cbor output. See above comment
