Log external external doesn't work in proton local

[jovezhong]

Describe what's wrong

I want to use proton local mode to monitor local logs and it reports error

Code: 48. DB::Exception: log external stream is not supported yet. (NOT_IMPLEMENTED)

How to reproduce
use homebrew version or directly download of proton binary
start it with proton local
run the following commands:

CREATE EXTERNAL STREAM log(
                      raw string
                    )
                    SETTINGS
                    type='log',
                       log_files='com.docker.backend.log',
                       log_dir='~/Library/Containers/com.docker.docker/Data/log/host',
                       timestamp_regex='^[(\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}\.\d+Z)]',
                       row_delimiter='(\n)'

Error message and/or stacktrace
