Update der-parser requirement from 6.0.0 to 8.1.0

[dependabot[bot]]

Updates the requirements on der-parser to permit the latest version.

Changelog

Sourced from der-parser's changelog.

8.1.0

Changed/Fixed

• Upgrade asn1-rs to 0.5.0 (new features only: only increment minor number)

8.0.0

Changed/Fixed

• Upgrade asn1-rs to 0.4.0 This causes an increment of the major number, because asn1-rs is re-exported

7.0.0

This release marks the beginning of the merge with the asn1-rs crate. This will break things.

However, this is necessary, because the asn1-rs crate is much cleaner and supports more types and features (like serialization, custom derive, etc.). Ultimately, this crate will become a frontend to asn1-rs, that will be optional: crate users can switch to asn1-rs and use it directly.

Changed/Fixed

MSRV: The minimum supported rust version is now 1.53.

BerObjectHeader:

• BerSize has been renamed to Length
• BerClass has been renamed to Class
• BerTag has been renamed to Tag
• Header fields are now private. Getters/setters have been added, and must be used to access/modify fields

BerObjectContent:

• Unknown variant now contains an Any object, with both the header and object content
• Private variant has been merged into Unknown
• BmpString, GeneralString, GraphicString, T61String, VideotexString and ObjectDescriptor are now decoded
• GeneralizedTime and UtcTime are now decoded

BerError:

• Add error types UnexpectedClass and UnexpectedTag
• Store expected and found item in error to help debugging
• Keep InvalidTag for tags with invalid form (length/encoding/etc.)
• Use displaydoc for BerError
• Parsing an indefinite length in DER now raises IndefiniteLengthUnexpected
• Error: when a DER constraint fails, store constraint identifier

DER:

• DerClass and DerTag have been deprecated. Use Class and Tag instead.
