Resolve "Update PLC project to match new topology of stirling slaves"

Closes #107

See merge request !184

After susbsitution of broken EL1502 slave, its subsitution was positioned in
differen position in the striling PLC K-Bus. This commit changes the mapping
in the PLC stirling project to address the new topology

Implemented blower activation. New parameter `blowerOpMode` allows to choose
between the legacy mode (`bm-reactive`) and the new one (`bm-preventive`)

Resolve "System enters in error when dish moves"

Closes #103

New parameter `minParasiteWaterFlow` sets the threshold for which in `Off` state
a flow is identified as parasite. Cooler than stays in `OffWithParasiteFlow` as long a timeout occurs or the flow goes below `flowEpsilon`

Some minor changes where applied:
*   Rename OffCirculatingFlow -> OffWithParasiteFlow
*   Put lbl_check_water in a standalone block
*   Reset timer when going from OffWithParasiteFlow to Off

Some minor changes where applied:
*   Rename OffCirculatingFlow -> OffWithParasiteFlow
*   Put lbl_check_water in a standalone block
*   Reset timer when going from OffWithParasiteFlow to Off
*   Add hysteresis in Off <-> OffWithParasiteFlow to avoid instability when
    around the edge. For this a new parameter "to-CheckParasiteWaterFlow" in
    DataView.asn and a new timer "pf_ck" in InterfaceView.aadl were added
