feat: scrape basal rate from diasend website

[burnedikt]

This serves as an example on how to obtain additional diasend data (like basal profile) from the diasend website instead of the API (since the API doesn't provide the desired data, also see #1).

Scraping is definitely not ideal as the website could change but I don't expect that to happen considering the switch to glooko at some point.

Either way, it can be used like:

import { getPumpSettings, getAuthenticatedScrapingClient } from "./diasend";

const username = "my.user@diasend.com";
const password = "super-secret-password";

const { client, userId } = await getAuthenticatedScrapingClient({
  username, password
});

console.log(await getPumpSettings(client, userId));

>>> [
>>>  [ '00:00:00', 1.2 ],
>>>  [ '01:00:00', 0.8 ],
>>>  [ '05:00:00', 0.5 ],
>>>  [ '08:00:00', 0.3 ],
>>>  [ '11:00:00', 0.5 ],
>>>  [ '13:00:00', 0.6 ],
>>>  [ '15:00:00', 0.8 ],
>>>  [ '19:00:00', 1 ]
>>> ]

Update: It can now fetch the following pump settings from diasend and forward them to the nightscout profile (or do something else with it):

• Basal Profile
• I:C profile (Insulin / Carb Ratio)
• ISF profiel (Insulin Sensitivity Factor)
• Low / High targets for blood glucose
• units configured in diasend (mg/dl or mmol/l)
• insulin on board time (in hours)
