Read a list of binary ids from a profile that consist of a.

uint64_t binary id length b. uint8_t binary id data c. uint8_t padding (if necessary) This function is shared between raw and indexed profiles. Raw profiles are in host-endian format, and indexed profiles are in little-endian format. So, this function takes an argument indicating the associated endian format to read the binary ids correctly.
