fix(users/flokli/archaeology): don't use file but column compression r/6994
Clickhouse also has column compression, configurable with the
output_format_parquet_compression_method setting.

It defaults to lz4, and the previous setting got a a zstd-compressed
parquet file with lz4 data.

Set output_format_parquet_compression_method to zstd instead, and sort
by timestamp before assembling the parquet file.

The existing files were updated to the same format with the following query:

```
SELECT * FROM file('bucket_logs_2023-11-11*.pq', 'Parquet', 'auto') ORDER BY timestamp ASC INTO OUTFILE 'bucket_logs_2023-11-11.parquet' SETTINGS output_format_parquet_compression_method = 'zstd'
```
