### Get files from Telegram
##### download_file
`download_file` download a file to DATADIR and returns the PATH to the file, main use is to download files send to chats.
I tried to be as compatible as possible with old function `download`.
*usage:* download_file path_to_ile prosed_filename
*alias*: download
*Note:* You must use `download_file` to download `URLS[...]` or `SERVICE[NEWPHOTO]` URLs from Telegram server.
*example:*
```bash
########
# download from Telegram server
# photo received in a chat
photo="${URLS[PHOTO]}")"
echo "$photo" -> photo/file_1234.jpg
# first download
file="$(download_file "${photo}"
echo "$file" -> ./data-bot-bash/photo-file_1234.jpg
# second download
file="$(download_file "${photo}"
echo "$file" -> ./data-bot-bash/jkdfhi-photo-file_1234.jpg
