Detect Format and Schema from Stdin in ClickHouse Local

Why it matters

This feature allows clickhouse-local to infer the input data format and schema directly from the data provided via stdin, removing the need for manual specification. It simplifies data loading workflows by enabling seamless and flexible processing of various input formats without prior format declaration.

How to use it

When running clickhouse-local, provide the input data through stdin without explicitly specifying the format or schema. The tool will automatically detect and apply the correct format and schema based on the input data.
