Release v2.2.1

Hotfix for protobuf producer.
When configuration was not passed, did not parse the packet.

fix:

* should parse with empty config #347

Release v2.2.0

The protobuf producer refactor and move to slog.
This version contains various fixes and improves mapping of encapsulated data.

fixes:

* mpls labels in NetFlow (#345)
* udp receiver not passing errors (#323)

features:

* add reload option for systemd service (#340)
* add more protocols to renderer (#341)
* refactor encapsulation and configuration (#342)
* use slog instead of logrus (#199)

The protobuf producer refactor allows more flexibility in terms of parsing of encapsulated protocols.
For instance SRv6, IPIP, MPLS, GRE, etc.
It also improves configuration handling for a better use as a library.
