build(deps): bump base64 from 0.22.1 to 0.23.1

[dependabot]

Bumps base64 from 0.22.1 to 0.23.1.

Changelog

Sourced from base64's changelog.

0.23.1

• Make the tests build again on non-SIMD architectures

0.23.0

• Added more consts for preconfigured configs and engines
• Make DecodeError::InvalidLastSymbol more clear by including the decoded value
• Added SIMD-accelerated engines behind the default-on simd-unsafe feature: Simd picks the best instruction set at runtime (AVX2 on x86_64, NEON on aarch64) and falls back to the scalar GeneralPurpose engine, while Avx2 and Neon target one instruction set with no runtime detection and work in no_std. The engines support the standard and URL-safe alphabets.
• Update MSRV to 1.71.0
• Add support for custom padding symbols
