Update litrs requirement from 0.4.0 to 1.0.0

[dependabot]

Updates the requirements on litrs to permit the latest version.

Release notes

Sourced from litrs's releases.

v1.0.0

As announced, this is basically just v0.5. I'm really happy to finally have litrs in v1.x state, as the library was already fit for production usage for a long time. Now the version reflects that.

• Breaking: Mark Literal as #[non_exhaustive]
• Document semver guarantees

[1.0.0] - 2025-10-20

As announced, this is basically just v0.5. I'm really happy to finally have litrs in v1.x state, as the library was already fit for production usage for a long time. Now the version reflects that.

• Breaking: Mark Literal as #[non_exhaustive]
• Document semver guarantees

[0.5.1] - 2025-08-01

• Add Literal::raw_input

[0.5.0] - 2025-07-25

Note: this is supposed to be essentially a 1.0 release candidate. If there are no problems with this release, it will be released as 1.0 after some time.

• Breaking Bump MSRC from 1.54 to 1.56
• Breaking: Remove proc-macro2 from default features
• Breaking: Make StringLit<String>::into_value return String instead of Cow<'static, str>. Make ByteStringLit<String>::into_value return Vec<u8> instead of Cow<'static, [u8]>.
• Add support for C string literals (also breaking due to new enum variant)
• Limit number of # as delimiter of raw string literals to 256 (to align with spec)
• Fix license in Cargo.toml to use proper SPDX format (in #19, thanks @​atouchet)
• Fix error span for InvalidStartOfUnicodeEscape errors

[0.4.2] - 2025-07-25

• Fix incorrect byte string value with non-ASCII \xHH byte string escapes
  • ByteStringLit::parse(r#"b"\xff""#).unwrap().value() would return [0xc3, 0xbf] instead of [0xff].
• Remove CR LF normalization to align with spec
  • This is technically a breaking change, but released with a minor version bump as it just aligns with the specification. It is extremely unlikely to affect any real world use case.
• Fix incorrect error span for out-of-range Unicode escapes

[0.4.1] - 2023-10-18

• Fixed incorrectly labeling 27f32 a float literals in docs.
• Added hint to integer literal docs about parsing as u128.

[0.4.0] - 2023-03-05

Added

• Add ability to parse literals with arbitrary suffixes (e.g. "foo"bla or 23px)
• Add suffix() method to all literal types except BoolLit
• Add IntegerBase::value
• Add from_suffix and suffix methods to FloatType and IntegerType
• Add FromStr and Display impls to FloatType and IntegerType

Changed

• Breaking: Mark FloatType and IntegerType as #[non_exhaustive]
• Breaking: Fix integer parsing for cases like 27f32. Literal::parse and IntegerLit::parse will both identify this as an integer literal.
• Breaking: Fix float parsing by correctly rejecting inputs like 27f32. A float literal must have a period OR an exponent part, according to the spec. Previously decimal integers were accepted in FloatLit::parse.
• Improved some parts of the docs
