Riven BLST resources
They control which hotspots should be enabled and which disabled within the card.
Each BLST resource is a list of records; it starts with an unsigned short record count, followed by that many records. The record size is 6 bytes and follows this structure:
|unsigned short||index||Record index, starting from 1|
|unsigned short||enabled||Hotspot state, 0 or 1|
|unsigned short||hotspot_id||Matches the blst_id field of the corresponding hotspot record|
BLST records must be "activated" from scripts, with command 43. Note that hotspots may exist without an associated BLST record. In that case, unless they are marked as Zip Mode hotspots and Zip Mode is off, they should just be enabled when entering the card.
