[NEW FEATURE] Timestamping management allowing synchronized network, or not.

[nicolas-rabault]

Details

Luos engine have been made for simple microcontrollers. Since version 3.0.0, Luos have been unleashed and able to run anywhere and use any network.

Historically to manage timestamping Luos was considering that no synchronization was available among the nodes. This is not true anymore because some advanced network can rely on time synchronization.

Describe the expected behavior of the feature

To be able to benefits from these synchronized network we have to be able to remove the latency based timestamping and use a plain date instead. This need to be a phy choice depending on it's capabilities.

this will be a boolean value stored in the luos_phy_t struct. This boolean will change the behavior of the Phy_ComputeMsgTimestamp, instead of computing the differential value we will just return the plain timestamp.
