mip / package.json: Allow 'deps' to come from another repository

Problem

In repo https://github.com/hmaerki/experiment_micropython_mip, I create a mip-package which may be install as follows:

import mip
mip.install("dryer2023", version="main", index="https://hmaerki.github.io/experiment_micropython_mip")

This is the package.json file:

{
    "version": "0.1",
    "hashes": [
        ["dryer2023/statemachine.mpy", "a47f24f2064b"],
        ["dryer2023/__init__.mpy", "c4104085da6d"]
    ],
    "deps": [
        ["umqtt.simple",  "latest"]     <== ERROR A
        ["https://micropython.org/pi/v2/package/6/umqtt.simple/latest.json",  "dummy"]  <== ERROR B
    ]
}

The installation of the hashes works nice.

In the deps section, I would like to install umqtt.simple from another index (the micropython default) but I could not make it working.

• ERROR A: Will search in my index (https://hmaerki.github.io/experiment_micropython_mip) which is wrong.
• ERROR B: This will correctly download 'latest.json' but then again will try to get the mpy-files from my index which is wrong.

Proposed: Solution

["umqtt.simple", "latest"] should always search in https://micropython.org/pi/v2
["github:org/repo/path/latest.json", "latest"] should search in github:org/repo/path/latest.json

Are there other suggestions/thoughs?

Inizia tracciando mip.install e la gestione delle dipendenze di package.json descritta nell’issue, incluso il modo in cui vengono risolti gli hash e gli URL dei pacchetti delle dipendenze. Il lavoro è completo quando le dipendenze possono essere ottenute dall’indice predefinito o da un altro repository senza recuperare erroneamente i relativi file mpy dall’indice del pacchetto padre, e le forme di dipendenza proposte si comportano come specificato.
