UserWarning: MessageFactory class is deprecated

[salsabeel-imagry]

Problem Description

Hi,

Seems that the "MessageFactory" class is deprecated, and I got the following warning when reading channel data

/usr/local/lib/python3.8/dist-packages/ecal/proto/helper.py:72: UserWarning: MessageFactory class is deprecated. Please use GetMessageClass() instead of MessageFactory.GetPrototype. MessageFactory class will be removed after 2024.
return google.protobuf.message_factory.MessageFactory(desc_pool).GetPrototype(desc)

How to reproduce

Here is a sample code for reproduction:

import ecal
from ecal.measurement.measurement import Measurement

measurement = Measurement("/path/to/measurement/file.hdf5")
channel =  measurement[measurement.channel_names[0]]
# or
channel = measurement['myChannelName'] 

reproduction
