• this PR addresses the issue #24

This PR add command line option "minCapacity" and related logic to filter appointments which have minimum available vaccination capacity. The default value is 1.

Real-world use case is that i am looking for 2 vaccination slots but getting lot of alerts with 1 slots.

This PR address the feature request https://github.com/PrasadG193/covaccine-notifier/issues/20.

A common function isPreferredAvailable() is used to check fee and vaccine preferences.

This PR adds the new option interval to change search query interval and improves logging

Refactored on top of - https://github.com/PrasadG193/covaccine-notifier/pull/7

• decide userMinAgeLimit on the basis of input --age value
• send notification only if userMinAgeLimit matches with vaccine availability for that minAgeLimit
• This PR address the issue #43

Ability to narrow down the search criteria by one or two center IDs would be useful.

Example

covaccine-notifier --state Maharashtra --district Akola --age 27 --email <email-id> --password <email-password>

A district wide search for district_id=364 results in 42 centers.... This query results in a flood of email alerts every time a slot opens up.

I just care about center_id:614986 , its just down the road. The alerts for those 41 other centers in my district just result in notification-fatigue :)
