Formatting breaks when using '\'

[buutqn]

The following queries are formatted using SqlFormatter:format() method

SELECT 
    path, 
    CHARINDEX(
        '\', path_sep) AS sep FROM dirs AS d

SELECT 
    path, 
    '\' AS sep FROM dirs AS d

This is sadly true as the https://github.com/jdorn/sql-formatter/blob/v1.2.17/lib/SqlFormatter.php#L339 and even https://github.com/doctrine/sql-formatter/blob/1.2.0/src/Tokenizer.php#L984 string tokenize code assumes MySQL grammar.
