[!104][SIMULTANEOUS] Adaptation of SimulST agents to the new SimulEva…

…l version

# Why is the change needed?
With the new version of SimulEval 1.1.0, all agents' codes do not work anymore.

# What changes does the patch introduce?
Introduce a new version of the agents which works with the new SimulEval version. The main parts of the code are still the same but the interaction with SimulEval has changed:

1. more than one token can be directly passed to SimulEval through `WriteAction()`, thus the output given to the tool must be "ready to show", i.e. de-tokenized and with correct spacing between words;
2. customized agents must inherit from `SpeechToTextAgent` class to be able to work with this new version;
3. `AgentStates` has its own structure in the SimulEval tool and customized states must inherit from it.

# How was this patch tested?
UTs and manual runs.
