zoom-lomax: download Zoom recordings

This is a very simple utility, designed to be run from cron daily, which will collect "field recordings" from your Zoom acccount.

It will download any recordings found in the last "days" days, as calculated with the meeting's local timezone.

To use, populate ~/.zoom-lomax like this:

{
    "api_key": "sdk_api_key",
    "api_secret": "sdk_api_secret",
    "user": "zoom_user_email@example.com",
    "output_dir": "/home/user/zoom-recordings/",
    "days": 1,
    "notify": "Your Name <you@example.com>"
}

days and notify are optional, with the former defaulting to 1 day.

(You can also use the -c command-line option to specify a different config file.)

They don't make it obvious, but you will need a Pro account in order to be able to get the key and secret. The account owner has to follow the steps described here:

https://marketplace.zoom.us/docs/sdk/native-sdks/preface/sdk-keys-secrets

under "Create new SDK credentials".
