Add getChipletNumber to Target Class

Chiplet Ids are as follows:
    - EQ 0-5     Ids: 0x10 - 0x15
    - EX 0-11    Ids: 0x10, 0x10, 0x11, 0x11, --- (parent's id)
    - Cores 0-23 Ids: 0x20 - 0x37
    - Pervasive  Id:  0x01
    - Xbus       Id:  0x06
    - Mcbist 0-1 Ids: 0x07 - 0x08
    - Mcs 0-3    Ids: 0x07, 0x07, 0x08, 0x08 (parent's id)
    - Mca 0-3    Ids: 0x07, 0x07, 0x07, 0x07 (parent's id)
    - Mca 4-7    Ids: 0x08, 0x08, 0x08, 0x08 (parent's id)
    - Obus0      Id:  0x09
    - Obus3      Id:  0x0C
