[IOTOF]: Updates in the TOF digitization for ALICE3

[GiorgioAlbertoLucia]

Main updates:

• the digitization is done by storing the information from the hits to the chips first. Then the digits are constructed

• the digitizer reader and writer were updated to store all the relevant information to the tree (previously commented)

• the full digitization procedure was finished and tested

• a simulation was run locally to test the writing of digits:

  • a pion gun is used to illuminate a specific chip of the detector
  • the produced hits are visualized as points in the local coordinates of the chip
  • the stored digits are visualized as a th2. Both the row/column information and the x/z position were visualized. A plot with the turned on pixels (from the digits) with the superimposed hits was also visualized, to check that the information would match.
