Mailpit: baixar versões antigas

## This release includes security fixes, so upgrading is strongly recommended.
A maliciously crafted image attached to an email could make the thumbnail generator (used by the web UI and API) spin in an infinite loop. The exif reader has been replaced with a minimal in-tree EXIF orientation reader that only reads the first block and never follows pointers.

This release also strips `<base>` and meta refresh tags from `/view/{ID}.html` output, and limits concurrent HTTP, SMTP and POP3 connections to 1000 each.

Due to timing, these security fixes have released together with new UI features in this release.

### Security
• Replace goexif with minimal EXIF orientation reader ([GHSA-379p-g4f4-hq5h](https://github.com/axllent/mailpit/security/advisories/GHSA-379p-g4f4-hq5h))
• Strip base and meta refresh tags from /view/{ID}.html output
• Limit concurrent SMTP, POP3 and HTTP connections to 1000 each

### Feature

## This release includes a security fix, so upgrading is strongly recommended.

A vulnerability was fixed which allowed animated image attachments (APNG, GIF, WebP) to bypass the thumbnail pixel budget, potentially causing multi-gigabyte memory allocation when the thumbnail was rendered.

Many thanks to the security researcher who responsibly disclosed this issue and helped improve Mailpit's security.

### Security
