Complete library

[RandomModderJDK]

Hi,
just wanted to use this project in another project, but I thought it would be nice if it would be modernized. So that's why I wanna try to make it to a package.
PS: At first, I wanted to code my own untis client, but you already did. Thx

A summary:
Added a pubspec.yaml
Applied package template
Reformatted file
(Hopefully) improved readability
Upped version requirements
Now in Flutter 3

Hey @RandomModderJDK, thanks for your pull request! I looked through the changes you made, and it seems like a good idea to modernize the package structure.

My only nitpick is the reformatting of the README, as I think that the spreading out assignments / function calls over multiple lines, makes the code less readable. E.g.:

var myId = (await mySession.searchStudent("demo_forename", "demo_surname"))!.surnameMatches![0].id;

was reformatted to

var myId = (await mySession.searchStudent("demo_forename", "demo_surname"))!.surnameMatches!
[
0
]
.
id;

If you could revert the changes you made to the code snippets in the README, I would be happy to merge your pull request and publish a new release.
