remap global keys easily

[blaggacao]

Is your feature request related to a problem? Please describe.
Based on https://discuss.kakoune.com/t/key-maps-as-key-locations/1414, we want to make keymaps part of a consolidated global environment state in a way that users can encode different custom key layouts easily.

Describe the solution you'd like
For best onboarding experience, we might want a nixflk global keymap wizard, so that once nix-community/home-manager#1685 is implemented, we could tell people to run flk keymap (or a surrogate) in order to key their muscle memory aliases like so:

Press Left Pinky on home row position: ...
Press Left Pinky 1 Up from home row position: ...
Press Left Pinky 1 Down from home row position: ...

constructing:

{
  LPinky = "a";
  LRing  = "s";
  LRingUp = "d";
  LMiddleDown = "m";
  LMiddle = "h";
  RMiddle = "e";
  RMiddleDown = "l";
  RRingUp = "p";
  RRing = "o";
  RPinky = "i";
}

Describe alternatives you've considered
This should actually be a standalone implementation, I'm putting a thought anchor here so it can be conceived in the context of making nixflk even more stellar.

Additional context

• We need a global keymap nix-community/home-manager#1685
• https://discuss.kakoune.com/t/key-maps-as-key-locations/1414

If we keep this nix specific, it's a great marketing argument for the whole community as for system configuration management. That would be pretty awesome, huh?
