Icon and SMTP Debug fixes.

Browse Source 
- We need to add some feature to enable smtp debugging again. See: https://github.com/lettre/lettre/pull/584
- Upstream added the fallback icon again, probably because of caching ;). See: https://github.com/bitwarden/server/pull/1149
- Enabled gzip and brotli compression support with reqwest. Some sites seem to force this, or assume that because of the User-Agent string it is supported. This caused some failed icons.

Fixes #1540
