Add a new firmador module that replaces the previous

[ghost]

• Removed of previous signXML (already was deprecated) and firmarXML, reuse firmarXML module, file and function name for backwards compatibility.
• Removed cli-signer tool that relied on signXML. For those that want to try a command-line tool I suggest an external alternative where the new signer comes from (it does not ingest from stdin, but could be easily modified to support it): https://codeberg.org/fdelapena/xades-b-b-enveloped-signers/raw/branch/master/PHP/signer.php

Additionally:

• Fixed Docker image for PHP. Fixed compatibility with Podman.
• Removed some unused v4.2 XSD files found in the meanwhile.
• Miscellaneous documentation updates (URL updates, minimum PHP version requirements)

The new version is not fully backwards compatible as it requires the user to change firmarXML with firmador in the w parameter;

Also, there are several warning in the console.
