This commit removes the state-machine.js library. It can be remove as this library was mainly used to handle the import action process, and that it has been rewritten without the need of the library. Copyright mentions to the library have also been removed, since it is no longer necessary. closes odoo/odoo#106265 Related: odoo/enterprise#34249 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
