Terminable Loop Command 1.2.4

This small new patch was required to fix the compatibility of the package with the newly released Symfony 7.3.

The bug arose from the fact that, in this new minor release, the Symfony Console Command started implementing the SignalableCommandInterface, which unfortunately comprehends a handleSignal method, whose signature conflicts with our own. This is to be expected, since that signature basically implements the same feature, terminal signal handling.

To be fixed, this required a duplication of the class and a conditional autoload, so I hope to ditch this approach soon by dropping support for older Symfony versions (below 5.2 at least) and rely completely on the Symfony interface.

This is the full changelog:

• Fix support for Symfony 7.3 (#23)
