`KeyError: ('cmdline-tools','latest')` on `sdkmanager --install "cmdline-tools;latest"`

[Benjamin LOISON]

```
$ sdkmanager --install "cmdline-tools;latest"
Traceback (most recent call last):
  File "/usr/bin/sdkmanager", line 33, in <module>
    sys.exit(load_entry_point('sdkmanager==0.5.1', 'console_scripts', 'sdkmanager')())
  File "/usr/lib/python3/dist-packages/sdkmanager.py", line 1077, in main
    method(args.packages)
  File "/usr/lib/python3/dist-packages/sdkmanager.py", line 891, in install
    url = packages[key]
KeyError: ('cmdline-tools', 'latest')
```

The reason why I tried running above command is that when [installing `flutter`](https://docs.flutter.dev/get-started/install/linux#verify-your-install-with-flutter-doctor) we are invited to run `flutter doctor` which in my case returned:

```
...
[!] Android toolchain - develop for Android devices (Android SDK version 34.0.0)
    ✗ cmdline-tools component is missing
      Run `path/to/sdkmanager --install "cmdline-tools;latest"`
      See https://developer.android.com/studio/command-line for more details.
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/linux#android-setup for more details.

```

Using `sdkmanager` from [this source](https://developer.android.com/studio#command-line-tools-only) works fine.

This works for me in v0.6.4:

 ~ $ sdkmanager --install "cmdline-tools;latest"
Downloading https://dl.google.com/android/repository/commandlinetools-linux-11391160_latest.zip into /home/hans/.cache/sdkmanager/commandlinetools-linux-11391160_latest.zip
Unzipping to /tmp/.sdkmanager-olwn0xvm
Installing into /tmp/android-sdk/cmdline-tools/latest
