Add a "sqlite" dialect

[ad-si]

Add an SQLite dialect to /Language/SQL/SimpleSQL/Dialect.lhs

-- | SQLite dialect
sqlite :: Dialect
sqlite = addLimit ansi2011
  { diBackquotedIden = True  -- https://sqlite.org/lang_keywords.html
  , diSquareBracketQuotedIden = True  -- https://sqlite.org/lang_keywords.html
  }

This should also include the new strict keyword (https://sqlite.org/stricttables.html)

SQLite also supports columns without types:

CREATE TABLE simple (a, b, c)
