v20.49

Support for FLUKA VMC backend in O2

This commit provides support for FLUKA in O2.
FLUKA compilation is optional for the moment.

This backend can be selected via:

```
o2-sim -e TFluka ...
```

v1.3.0

Update release.yml

v1.2.0

DPL: introduce exponential backoff when idle

This should reduce the amount of CPU used by data processors when they are idle
while retaining the ability to increase back the rate, should it be needed.

First stable release

fix unitialized variables in an EMCAL exception

Now giving proper error log when the exception occurs
