Issue Description

I'm seeing an issue with 2.25.0 where it's possible to be unable to import a map that was previously exported by the T265.

To reproduce this in the viewer all I have to do is start and map an area, then stop and export that map. Then import the same file I exported and see if it was successful. If it was successful I run the device for a little with the imported map until it relocalizes. Then stop and repeat the steps from the beginning. After roughly five times the map import fails with the message below.

Invalid Value in rs2_import_localization_map(sensor:0000022AA6265BE0, lmap_blob:R, blob_size:849021):
import localization failed, map size 849021

Thanks.
