A menu in PeaZip showing which options have high compression and which are fast

SUMMARY
When creating an archive, Ark offers several archive formats and compression algorithms, but gives no help about which to choose. Some extra information could be given in the menu, like PeaZip does (see attached screenshot), or perhaps a help button nearby. The compression/decompression speed and a rough idea of compression ratio is the key information here, but some algorithms could have an extra note about compatibility with other software, or whether they are especially well suited to a particular type of file, etc.

STEPS TO REPRODUCE
1. Open Ark
2. Click New Archive
3. Open the Type: menu and imagine you don't know anything about compression algorithms

OBSERVED RESULT
No help with choosing an archive type

EXPECTED RESULT
Some help with choosing an archive type

There are two parts:
* Information on choosing an archive format (e.g. ZIP, tar, 7z, RAR)
* Information on choosing a compression algorithm (e.g. Zstandard, Deflate, LZMA, bzip2)
