Error reading config.yaml

Describe the bug
If in config.yaml

exchanges:
    BITFINEX:
        l2_book:
            symbols: [ BTC-USD ]

error:

Process Collector-1:1:
Traceback (most recent call last):
  File "C:\Python38\lib\multiprocessing\process.py", line 315, in _bootstrap
    self.run()

    raise ValueError("Use subscription, or channels and symbols, not both")
ValueError: Use subscription, or channels and symbols, not both

If in config.yaml

exchanges:
    KRAKEN:
        l2_book:
            symbols: [ BTC-USD ]

no errors, it works.

Feedhandler gets an unnecessary list symbols, if exchanges is Bitfinex.

Operating System:
Windows

Cryptofeed Version
cryptofeed 2.1.1

Cryptostore Version
cryptostore 0.4.0

I do have the same problem with Hitbtc when I try to fetch the l2_book:

exchanges:
    HITBTC:
        l2_book:
            symbols: [ BTC-USDT ]
