[bug] File tree can take a long time to load #651
Description
Describe the bug
For larger repositories, the file tree can take upwards of 10-20 seconds to load.
To reproduce
Open a larger project in browse.
Sourcebot deployment information
Sourcebot version (e.g. v3.0.1): latest
Additional information
My guess is that the bulk of the time is in the ls-tree command, as well as transmitting the large json blob. We could probably only load in a subset of the information, and then dynamically request additional data as the user expands folders.
