tracks_manager serialization error

[CosmosHua]

from opensfm.dataset import DataSet
data=DataSet('xxx/odm-RTK/opensfm')
t=data.load_tracks_manager()
t.as_string()
---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)

RuntimeError: Serialization from string not supported

As above, in the 286 branch of this OpenSfM, an error occurs when I try to serialize a tracks_manager, because you binarized the tracks.csv file.

@CosmosHua Apologies for the delay in the answer; this slipped through the cracks for too long.

This is one of the changes ODM does over native OpenSfM, we use files directly and our own binary versions. This saves an entire copy (string and then serialise)
