update sliding-window clustering for Theta-Module readout

[dasphy]

Hello,
I create this PR for making sliding-window clustering work with Theta-Module readout.
Please help me review the code, thank you!

Hello @vvolkl @BrieucF @kjvbrt,
In this PR I added a new file "k4Interface/ITowerToolThetaModule.h" for SW clustering at FCCee,
where CaloTower is created from theta-phi that is different from eta-phi segmentation at FCChh.
Please have a look, thank you.

Hello @dasphy, can you remove the struct tower from this interface?
Similarly to the #175
