It is useful for other OPTIONAL fields that does not have a context tag. For
example, `keyLength` inside
PBKDF2-params ::= SEQUENCE {
salt CHOICE {
specified OCTET STRING,
otherSource AlgorithmIdentifier {{PBKDF2-SaltSources}}
},
iterationCount INTEGER (1..MAX),
keyLength INTEGER (1..MAX) OPTIONAL,
prf AlgorithmIdentifier {{PBKDF2-PRFs}} DEFAULT algid-hmacWithSHA1
}
```
Maybe I should create a `getOptional(byte)` method?
