Allow symmetric key to be any non-empty bytes

[BrianSipos]

This closes #112 and closes #133 and adds algorithm-specific checks for key length.

The HMAC algorithms do not require an exact or minimum length because of the requirements of RFC 9053 state:

For those algorithms that transport the key (such as AES Key Wrap), the size of the HMAC key SHOULD be the same size as the output of the underlying hash function.
For those algorithms that derive the key (such as ECDH), the derived key MUST be the same size as the output of the underlying hash function.
