feat: named filter groups

[Insomniak47]

Since sometimes queries get a bit long we should add the ability in the config to specify named filters.

so instead of something like:

peer show -f !author:bot -f author:renovate -f whatever:whatever

we could have a section for "namedFilters" in the json that would allow you to do something like:

-f alias:notBots

with a section (under show?) like:

"Show": {
 "namedFilters": [{ "name": "notBots", "filter": " !author:bot !author:renovate whatever:whatever"}]
}
