    theme-parser: Use peek_required_version() for validation
    
    When validating button functions and frame styles, the required
    format version of the features used in the theme was compared to
    the major version number of the supported format, limiting additions
    to major theme format bumps.
    Use peek_required_version() instead, so the minor version number
    of the supported theme format is taken into account.
