The encoding picker should have a less confusing list and a way to search in it

[lhecker]

Editors such as VS Code rely on iconv, which we can't (binary size). Left with ICU, the problem is that it

• doesn't expose human readable names for its supported encodings
• the naming of the encodings doesn't always follow an easily understandable rule
• and it supports a lot of encodings

We should:

• Add fuzzy search (src/fuzzy.rs)
• Consider adding proper names for some of them (optional? how?)
• Consider adding the encoding aliases too ucnv_getAliases

Got a very interesting encoding of a powershell script when running over ssh at least ;)

The usage scenario is a small/quick script adjustment and logging on over ssh is way faster than rdp. Rdp makes no sense for a core installation anyway
