Install each Library Manager sourced library separately

`arduino-cli lib install` fails if one of the libraries in the list has a dependency on another, but an earlier version of the dependency is specified in the list.

For example, the following command doesn't install any libraries and returns exit status 1:

$ arduino-cli lib install [email protected] ArduinoIoTCloud
[email protected] depends on [email protected]
[email protected] depends on [email protected]
[email protected] depends on [email protected]
[email protected] depends on [email protected]
[email protected] depends on [email protected]
[email protected] depends on [email protected]
[email protected] depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
ArduinoIoTCloud depends on [email protected]
The library Arduino_ConnectionHandler is required in two different versions: 0.4.9 and 0.4.8

The solution is to install one library at a time (even though `arduino-cli lib install` supports installing multiple libraries at once). This also allows the user to control which version of the library is installed in the end by the order of the list passed via the libraries input.
