Add package dependencies to the repo

This is required for more complex packages that depend on each other. My proposal is to do the following format change:

{
  "dependencies": {
    "${import name 1}": "${package name 1}",
    "${import name 2}": "${package name 2}"
  }
}

This allows package managers to create a correct DAG out of the packages and build a correct std.build.Pkg structure. Import name is the name that needs to get passed to @import(…), package name is the file name in the repository without the file extension.

Example:

{
  "author": "truemedian",
  "description": "A WebSocket 1.3 library for Zig",
  "git": "https://github.com/truemedian/wz",
  "root_file": "/src/main.zig",
  "dependencies": {
    "hzzp": "hzzp"
  },
  "tags": [
    "networking"
  ]
}

My proposal is a bit unusual but here is what i propose: in a case where a package depends on another package but not its implementation (for example it might depend on a windowing package, but it might be a glfw or an x11 package), there should be a way for the user to choose which to use. Maybe for those case the dependency package name might be null, for example:

{
  "author": "zenith391",
  "description": "OpenGL module for Didot",
  "git": "https://github.com/zenith391/didot",
  "root_file": "/didot-opengl/graphics.zig",
  "dependencies": {
    "didot-window": null
  },
  "tags": [
    "game",
    "graphics"
  ]
}

When installing that package, the package manager should so something like prompt the user to select a package to install, and the user could type didot-x11, didot-glfw or any other windowing package he wants.

Counter-proposal to the comment by @zenith391:

{
  "dependencies": {
    "didot-window": [ "didot-x11", "didot-glfw" ]
  }
}

Which would allow a package manager to also prompt the user which package to install, but also list available and checked options. Note that this should not be an enforcement, but a hint. You should be able to override the selection anyways

As it seems people agreed on it, shouldn't this issue start getting implemented?

True! If you have the time, go ahead, implement it and make a PR! I will happily click merge!

It seems that current design doesn’t consider versions, which is important for reproducible build

Yes, but i refuse to do version tracking before Zig 1.0.0, as i consider that wasted energy, as your Zig code might break tomorrow anyways.
