Passwords with special characters do not work

[Insprill]

As noted in Depot Downloader's README, special characters need to be escaped when using the -password flag according to the shell being used. In theory, just wrapping it in double quotes as is done now should work, but it doesn't in practice. When my password had @, %, &, !, and $ in it, I could not log in. After removing all special characters, I could log in fine. BSLL v1.7.1, Windows 10 22H2
