[Feature Request] Provide a 'create a new project' functionality.

[zapta]

Platformio has the command pio project create that creates a complete and buildable skeletal hello world project. https://docs.platformio.org/en/latest/core/userguide/project/cmd_init.html .

Apio on the other hand has the command apio create that creates just an apio.ini file and theapio examples command that creates a non skeletal project and requires the user to manually select the example.

This feature request is for a command that accepts creates a full skeletal project for a given board. For example

apio new --board icezum

or

apio examples --board icezuum --new_project

Implementation wise, the new project can be added to the apio_examples repo as examples with the reserved name new_projects and for boards that don't have a new_project example, their definition can include new_project = <example-name> to indicate the example to use.

[zapta]

This can be an extension of the new 'apio create' command, and the startup project can be an adaption of the existing 'template' examples.
