For our experiments, we need to setup 500 tags. However, the tag_locations.conf only allows for using 64 tags (as shown here: https://docs.modalai.com/voxl-tag-detector/) . How can we change this behavior. We not that at any point in time, only 4-5 tags would be detected simultaneously. Our voxl sdk version is 1.5.1

Thanks!

@tejasram The source code is here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-tag-detector. Perhaps try changing `#define MAX_TAG_LOCATIONS  64` in `locations.h`.

@Eric-Katzfey Yes that worked. Thanks!
