Briefly, what does this PR introduce?

Endcap TOF geometry modified to match the newest technical drawings from https://indico.bnl.gov/event/24949/attachments/57520/98759/ePICTOF_WP2_FTOFLayout_09272024v2.pdf.

The current epic geometry has each ETOF module located separately. But the newest drawing shows that a single power board house multiple modules together. This PR groups modules together according to the aforementioned drawing.

Furthermore, the current epic geometry shows that sensors are placed facing front and backing alternatively across rows. However, the latest drawing shows that ETOF are double sided on every row, but with sensors placed below the service hybrid on the front side, and above the service hybrid on the other side. Each module now contains 4 small sensors instead of one big sensor.

Here's the updated ETOF power board configuration,

Here's the design drawing,

Barrel TOF is also modified. Staves are broken into two so an engagement ring can fit in the middle. LGAD is also located on both sides alternatively,

Cooling tubes are also incorporated into the staves,

Latest technical drawing shows that sensor width is half of what was previously proposed. Sensors right next to the central engagement ring are only half sized,
