File Downlink PermissionError crashes the GDS

Problem Description

If you donwnlink a file and it fails, for example due to permissions issues on the host, the GDS green dot will change to a red x and not recover.

How to Reproduce

1. Have another user downlink a file so that /tmp/fprime-downlink is only writable by that user
2. Attempt file downlink as a new user
3. Observe red x in GDS window

Expected Behavior

Generate an EVR that reports the permission issue and keeps running
Can fprime-gds be configured to either (1) make its directories group writable by default or (2) use a user's home directory for downlink? Otherwise, we all need sudo to keep changing permissions depending on who is downlinking

The issue is that when the GDS encounters a permissions issue, it shouldn't just crash. It should recover and keep running.
