build(deps): update minicbor requirement from 0.19 to 0.21

[dependabot]

Updates the requirements on minicbor to permit the latest version.

Changelog

Sourced from minicbor's changelog.

0.21.0

• ⚠️ Breaking ⚠️: Tag handling has been reworked (cf. merge request !34). The Tag type is now merely a newtype around a u64. A new enum IanaTag represents registered tag values.

0.20.0

• Support for decoding arrays of arbitrary length has been added (cf. merge request !31 by @​samuelmhicks).
• Added Encode and Decode impls for CStr and CString (cf. merge request !29).
• Added decode::info::Size to allow length introspection of CBOR values (see merge requests !25 and !28 for details).

0.19.1

• Bugfix release (see merge request !26 by @​jeandudey for details).

0.19.0

• Added the trait CborLen and functions minicbor::len and minicbor::len_with to allow client code to calculate the length in bytes of a value's CBOR representation. See issue #32 and merge request !23 for details.

0.18.0

• Remove feature partial-derive-support. Encode and Decode can always be derived. See commits 21060b3272d4d09af88aa8543f682c8c4477a886 and 9038d3cced197588ae4d8d2c891d6f51029a9e7d for details.
• Rework encode::Write impls. The blanket impl for types implementing std::io::Write has been removed. The impl for Vec<u8> now always uses Infallible as its error type and minicbor::{to_vec, to_vec_with} no longer require feature "std". See commit 498043ddce69e3da0dcc66593afdeea0dd058fb8 for details.
• Depend on minicbor-derive-0.12.0.

0.17.1

• Fix missing import for cargo feature derive.

0.17.0

• Remove cargo feature partial-skip-support. The method Decoder::skip is now always available. With cargo feature alloc, every CBOR item can be skipped over, otherwise attempting to skip over indefinite-length arrays or maps inside of regular arrays or maps will result in an error.
• Depend on minicbor-derive-0.11.0.

0.16.1

• Specialise Cow<_, [u8]> by adding implementations of minicbor::bytes::{EncodeBytes, DecodeBytes}.

0.16.0
