Are you sure we should use reliable for our high rate TF?

These are the subscribers. The XML did not specify a reliability for these topics
- /ap/joy
- /ap/tf
- /ap/cmd_vel
- /ap/cmd_gps_poseIf the default QoS (struct) initialised each of it's fields to 0 we get:
typedef struct uxrQoS_t
{
uxrQoSDurability durability = UXR_DURABILITY_TRANSIENT_LOCAL;
uxrQoSReliability reliability = UXR_RELIABILITY_RELIABLE;
uxrQoSHistory history = UXR_HISTORY_KEEP_LAST;
uint16_t depth = 0;
} uxrQoS_t;See create_entities_bin.h. Now I'm not certain that the XML is doing the same. Perhaps we should set reliability to BEST_EFFORT for all subscribers?
Switch to BEST_EFFORT in bf1962d

For these I think best effort to save resources.

Replace the
uxr_buffer_create_*_refmethods withuxr_buffer_create_*_bin. This eliminates the need for adds_xrce_profile.xmlon the agent side and simplifies future work to#ifdefmessages for inclusion as everything is now self contained theAP_DDSlibrary.Testing
