Unicorn-binance-websocket-api

Added
- new parameter `stream_label` in `manager.create_stream()`[issue 60](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/60)
- `manager.get_stream_label()` [issue 60](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/60)
- `manager.get_stream_id_by_label()` [issue 60](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/60)
- `manager.set_stream_label()` [issue 60](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/60)
- added `stream_label` to `manager.print_stream_info()` [issue 60](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/60)
- added `stream_label` to `manager.print_summary()` [issue 60](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/60)
- `manager.help()`
- `unicorn_binance_websocket_api_exceptions.py` with exception `StreamRecoveryError` and `UnknownExchange`
- `fill_up_space_right()`
- `self.restart_timeout`
Changed
- raising `UnknownExchange` or `StreamRecoveryError` instead of `ValueError`
- `fill_up_space()` to `fill_up_space_left()`
Fixed
- reset the payloads of a stream at a stream restart
- moved some code for a stream restart from `_keepalive_streams()` to `restart_stream()` which caused that the direct
call of `restart_stream()` worked only inside of `_keepalive_streams()`
- handling of `RuntimeWarning` in class connection at row 189
Removed
- code to start new `_keepalive_streams()` and `_frequent_checks()` threads

Added
- `disable_print` in `print_summary()` [pull 48](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/pull/48)
- `print_summary_export_path` - if provided, the lib is going to export the output of `print_summary()` to a PNG image.
- `get_number_of_all_subscriptions()` and show all subscriptions number in `print_summary()`
Fixed
- ping listen_key if "!userData" is in `channels`, not only in `markets`.
- format of some logs
- stream buffer size [issue 51](https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/issues/51),
