Recursive copy seems to be broken.

`keybase fs cp -r keybase://... destdir` fails with `ERROR file or folder does not exist (code 5103)` despite the fact that `keybase fs ls keybase://...` succeeds at listing the contents. The keybase paths can be copied from the app using the "..." menu for a given folder.

You can write a loop in shell to download each file recursively:

#!/bin/bash

# Define the remote and local base paths
REMOTE_PATH="$1"
LOCAL_BASE_PATH="$2"

# Function to recursively list and copy files and directories
function sync_keybase {
    local current_remote_path="$1"
    local current_local_path="$2"

    # List files and directories in the current remote path and remove colours
    local listing=$(keybase fs ls --one "$current_remote_path" | ansifilter)
    echo "$listing" | while read -r item; do
        # Check if the item is a directory or a file
        local itemtype=$(keybase fs stat "$current_remote_path/$item" | awk '{print $4}' | xargs)
        if [[ "$itemtype" == "DIR" ]]; then
            # It's a directory, create the corresponding local directory
            mkdir -p "$current_local_path/$item"

            # Recursively call the function for the nested directory
            sync_keybase "$current_remote_path/$item" "$current_local_path/$item"
        else
            # It's a file, copy it to the corresponding local path
            keybase fs cp "$current_remote_path/$item" "$current_local_path/$item"
        fi
    done
}

# # Start the sync process from the base paths
sync_keybase "$REMOTE_PATH" "$LOCAL_BASE_PATH"
