build(deps): update peg requirement from 0.6 to 0.7

[dependabot-preview]

Updates the requirements on peg to permit the latest version.

Release notes

Sourced from peg's releases.

0.7.0

New features

• Significantly improved compile-time error messages for invalid grammars
• Support [MyToken(x)] syntax for capturing variables from pattern expressions (#245)
• Restore support for [^ ] inverted pattern syntax
• Add #[no_eof] pub rule() = ... syntax to allow matching a prefix of the input rather than reporting a parse error if the rule does not reach end-of-file (#233)
• Allow rule _ = without parentheses when defining special underscore rule (#243)
• Add grammar-level type and lifetime parameters (#254)
• Compile-time check for repeat expressions that infinite-loop without consuming input (#210)
• Implement PartialEq, PartialOrd, Eq, Ord, Debug, Hash for RuleResult (#217)

Fixes

• Extend detection of infinite-loop left recursion to check inside precedence!() (#238)
• Wrap user-supplied code in immediately-invoked closure so that return and ? behave as expected (#246)
• Remove overzealous error checks to allow passing rule closure arguments as parameters to another call (#226)

Breaking changes

• Add required is_eof() method to Parse trait (#252)
• Certain patterns that would infinite-loop or stack overflow if executed are now a compile-time error
• mixed_site hygiene prevents action code from accessing internal parser state variables such as __input, __pos, etc.
