Geometry IDs

The geometry description is gives us that each pad is identified by plane, ring, pad:

• plane The mTPC will consist of 10 separate TPC volumes. Numbered 0 - 9 from upstream to downstream.
• ring The pads are arranged into 21 concentric rings, The rings are numbered from 0 to 20 sequentially, with 0 being the innermost ring.
• pad Each ring has 122 pads, 0 is at or closest to phi=0 and numbering is clockwise

This is convenient to encode in a singe uint32_t ID.

1 000 000 * plane + 1 000 * ring + pad
