[bug] Skip correct number of escape characters

[ianlewis]

The correct escape characters in strings should be skipped. The current code skips a single character if an escape character is detected but it should skip as many characters as needed.

todos/internal/scanner/scanner.go

Lines 319 to 322 in 308b0db

	// Skip the backslash character.
	if _, err := s.reader.Discard(1); err != nil {
	return st, fmt.Errorf("parsing string: %w", err)
	}

The escapeFunc should return the characters (or number of characters) that were escaped instead of just a bool.

type escapeFunc func(s *CommentScanner, st *stateString) (bool, error)

This doesn't really seem to be an issue for any supported languages.
