Consumer fails when consuming messages compressed with ZSTD at the broker level

**Describe the bug**
When consuming messages from a broker where compression has been set at the broker level with ZSTD compression, the Consumer fails with an UnknownError. This does not happen when ZSTD is set at a producer level instead. **This behaviour is observed both in the latest pypi release, as well as in the latest version from the master branch in this repository**

**Expected behaviour**
Consumer should be able to consume messages with ZSTD compression, when its set at a broker level, just the same as when its set at a producer level.

**Environment (please complete the following information):**
- aiokafka version: 0.7.2
- kafka-python version: 2.0.2

**Reproducible example**
When setting up the Broker, add to the server.properties file
```
compression.type=zstd
```

On the contrary, when if compression.type is omitted in the server.properties file and instead you create a producer with zstd compression, it works fine.
