Clickhouse tuples not supported

Clickhouse tuples are not supported. The following errors `ParserError("Expected: end of statement, found: .1 at Line: 1, Column: 22")`.

```
SELECT t.1 FROM x
```

This is a valid Clickhouse way of accessing tuple elements. See https://clickhouse.com/docs/sql-reference/functions/tuple-functions#tupleelement. It is some syntactic sugar to `tupleElement(t, 1)` which does work.

Request: Make the above query work, and similar ones.

```
SELECT t.1 FROM x
SELECT (1, 2, 3).2
SELECT arr[1].1 FROM t
SELECT arr[1].1.2 FROM t
```

Start by reproducing the reported ParserError with the ClickHouse examples, beginning with `SELECT t.1 FROM x` and comparing it with the working `tupleElement(t, 1)` form. Extend support until the listed tuple, array, and chained-access queries parse successfully, then add or run parser coverage for those examples.
