Damien Elmes bb1b289690 Add some helpers to allow add-ons to install packages into the venv

While something we probably don't want to encourage much of, this
may enable some previously-unshared add-ons.

https://forums.ankiweb.net/t/bundling-numpy-in-an-add-on/62669/5

The 'uv add' command is transaction, so if an add-on tries to inject
incompatible dependencies into the environment, the venv will be
left as-is. And each Anki upgrade/downgrade resets the requirements,
so the requested packages shouldn't cause errors down the line.

Sample add-on:

import subprocess
from aqt import mw
from aqt.operations import QueryOp
from aqt.qt import QAction
from aqt.utils import showInfo

def ensure_spacy(col):
    print("trying to import spacy")
    try:
        import spacy
        print("successful import")
        return
    except Exception as e:
        print("error importing:", e)

    print("attempting add")
    try:
        from aqt.package import add_python_requirements as add
    except Exception as e:
        raise Exception(f"package unavailable, can't install: {e}")
    # be explicit about version, or Anki beta users will get
    # a beta wheel that may break
    (success, output) = add(["spacy==3.8.7", "https://github.com/explosion/spacy-models/releases/download/ko_core_news_sm-3.8.0/ko_core_news_sm-3.8.0-py3-none-any.whl"])
    if not success:
        raise Exception(f"adding failed: {output}")

    print("success")

    # alterantively:
    # from aqt.package import venv_binary
    # subprocess.run([venv_binary("spacy"), "download", "ko_core_news_sm"], check=True)
    # print("model added")

    # large packages will freeze for a while on first import on macOS
    import spacy
    print("spacy import successful")

def activate_spacy():
    def on_success(res):
        mw.progress.single_shot(1000, lambda: showInfo("Spacy installed"))

    QueryOp(parent=mw, op=ensure_spacy, success=on_success).with_progress("Installing spacy...").run_in_background()

action = QAction("Activate Spacy", mw)
action.triggered.connect(activate_spacy)
mw.form.menuTools.addAction(action)
