Update minicbor requirement from 0.7 to 0.8

[dependabot]

Updates the requirements on minicbor to permit the latest version.

Changelog

Sourced from minicbor's changelog.

0.8.0 (minicbor)

Change data::Type to distinguish between indefinite arrays, maps, bytes and strings, and regular ones by introducing constructors such as Type::ArrayIndef. This is potentially a breaking change for code that uses data::Type.

Add new types decode::Token and decode::Tokenizer to allow decoding CBOR bytes generically as a mere sequence of tokens.

Add a function display which displays CBOR bytes in diagnostic notation.

0.3.0 (minicbor-io)

Depend on minicbor-0.8.0.

0.7.2 (minicbor)

Bugfix: Type::read used 0xc9 instead of 0xc0 when reading Type::Tag. Add README.md

0.6.2 (minicbor-derive)

Add README.md

0.2.3 (minicbor-io)

Add README.md

0.2.2 (minicbor-io)

Use same version for minicbor dependency in dependencies and dev-dependencies.

0.2.1 (minicbor-io)

Reader and AsyncReader always return UnexpectedEof when reading 0 bytes while decoding a frame, unless at the very beginning of a frame, when not even the length prefix has been read, where Ok(None) would be returned instead. Previous versions returned Ok(None) while reading a partial length prefix.

0.7.1 (minicbor)

Require minicbor_derive 0.6.1.

0.6.1 (minicbor-derive)

Maintenance release.
