add download timeouts for PDSC entries, log error to STDOUT

[danieldegrasse]

Add a timeout of 5 seconds on downloads of PDSC entries, and log an error to stdout. This way broken PDSC entries do not hang the pyocd pack update command

Without this change:

$ pyocd pack clean
$ pyocd pack update
0000154 I Updating pack index... [pack_cmd]
Downloading descriptors (1611/1631) # command hangs here, does not complete

With this change:

$ pyocd pack clean
$ pyocd pack update
0000154 I Updating pack index... [pack_cmd]

Downloading descriptors (1631/1631)

Command completes and I can use the packs that downloaded correctly

+1! With this issue being present, it breaks some workflows like building containers that do a pyocd pack update.
