Adds a new example demonstrating the Proemion CAN Layer 2 library (V0.1.0.1) for signal-based logging using a delta-anchor threshold strategy. Includes the compiled library, a complete self-contained project archive (SalesDemo), and full documentation covering FB_CAN_Setup, FB_CAN_Rx_Signal_REAL, FB_DeltaAnchorTrigger, and FB_SignalTriggeredLogger. Also updates .gitignore and .gitattributes to support the .compiled-library file type.

| Instead of logging every CAN frame at a fixed rate, the library's `FB_DeltaAnchorTrigger` only fires when a signal deviates from its last logged value (the "anchor") by more than a configurable `Delta`. An optional `MinTime_ms` debounces fast oscillations around a threshold; `MaxTime_ms` forces a log entry even if the signal is stable — ensuring heartbeat records. | ||

|

| The `SalesDemo_Example` project shows this pattern across multiple CAN networks and signal types on a **Proemion CANlink mobile 10000** device. |

I propose to rename the Project to CANLayer2_Example.

Since this library is not an official product from Proemion I propose to rename it to something like CANlink_CAN and remove the name Proemion everywhere:

Since the way how libraries are being installed at CODESYS might change in the future I propose to refer to the way how libraries are installed in CODESYS.

Since the function block documentation is included in the library I propose to not have it also here. This would require to maintain it at both places.
