[cpackget] Confusing unaligned output cpackget update-index -a due to concurrent downloads

[jkrech]

Describe the bug
When running cpackget update-index -a there seems to be missing new lines in the output if concurrency of downloads kick in
Look for: [0s:0s]I: Downloading at the end of the line starting with I: 0% |
the I: Downloading should start at a new line.

I: Downloading all PDSC files available on the public index
I: Downloading Microchip.PIC32CM-LS_DFP.pdsc...
I: Downloading Microchip.PIC32CM-MC_DFP.pdsc...
I:   0% |                                                                                                                                                                                                                                   | ( 0 B/57 kB) [0s:0s]I: Downloading Microchip.SAMC20_DFP.pdsc...
I:   0% |                                                                                                                                                                                                                                  | ( 0 B/218 kB) [0s:0s]I: Downloading Microchip.SAMC21_DFP.pdsc...
