build(deps): update hex-conservative requirement from 0.2.1 to 1.1.0

[dependabot]

Updates the requirements on hex-conservative to permit the latest version.

Changelog

Sourced from hex-conservative's changelog.

1.1.0 - 2026-05-04

v1.0 of this crate only has the decoding side (and the decoding iterator is private).

This next release introduces the encoding side of the library and also makes the iterator types public - enjoy.

• Prepare master to be v1.1 #206
  • Delete serde module
  • Delete FromHex trait
• Convert DisplayHex to use GAT #215
• Bump MSRV to Rust v1.74.0
  • #216
  • #228
• Derive standard traits on all types #221
• Add FromIterator and Extend to BufEncoder #223
• Remove serde dependencies #224
• Convert HexSliceToBytesIter to a newtype instead of an alias #227
• Implement nth and nth_back #232
• Fix InvalidCharError position with mixed reading on HexToBytesIter #235
• Introduce Char enum and rewrite BytesToHexIter to return it #236
• Use Char table lookup to improve decode performance #243
• Char improvements #242
• Align fmt_hex_exact and Display impls #127

0.3.2 - 2026-01-28

• Add hex! macro for const hex literal parsing.
• Bump the MSRV

1.0.1 - 2025-12-02

• Remove doc_auto_cfg

1.0.0 - 2025-07-11

• Removed niche reexports from root
• Various documentation improvements
• A few test improvements

1.0.0 release candidate 2 -- 2025-06-27

• Removed iterator API that got published by accident

1.0.0 release candidate 1 -- 2025-05-16

• Exports decode_to_array, decode_to_vec, and all error types.

The goal of this release is to enable library authors to use hex-conservative, exposing error types from this library in their own APIs, and not need to worry
