feat: 0.2.10 Add feature for anvilPy, update init subcommand

[jgabaut]

• Puts AnvilKern::AnvilPy usage behind the anvilPy feature.
• Updates init subcommand to use the basename of passed directory for target name (before, it was "hello_world")
  • This may be handled strictly if needed, but for now we're just gonna break in this little aspect from amboso <=2.0.5.
