Update litrs requirement from 0.3.0 to 0.4.0

[dependabot[bot]]

Updates the requirements on litrs to permit the latest version.

Release notes

Sourced from litrs's releases.

v0.4.0

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

Removed

• Breaking: Remove OwnedLiteral and SharedLiteral

[0.3.0] - 2022-12-19

Breaking

• Bump MSRV (minimal supported Rust version) to 1.54

Added

• Add raw_input and into_raw_input to non-bool *Lit types
• Add impl From<*Lit> for pm::Literal (for non-bool literals)
• Add impl From<BoolLit> for pm::Ident

Fixed

• Fix link to reference and clarify bool literals (#7)

Internals

• Move lots of parsing code into non-generic functions (this hopefully reduces compile times)
• To implement [into_]raw_input for integer and float literals, their internals were changed a bit so that they store the full input string now.

[0.2.3] - 2021-06-09

Changed

• Minor internal code change to bring MSRV from 1.52 to 1.42

[0.2.2] - 2021-06-09

Changed

• Fixed (byte) string literal parsing by:
  • Correctly handling "string continue" sequences
  • Correctly converting \n\r into \n

[0.2.1] - 2021-06-04

Changed

• Fixed the expected value of the error returned from TryFrom<TokenTree> impls in some cases

... (truncated)
