Add modules

[tehw0lf]

The modules section is permanently open to pull requests to pwn more default keys!

A template module is included in modules. crackdefault.sh contains a template elif statement to include the new module.

Contributing a module generally means to gather an existing open source implementation that exploits a weak key algorithm for a specific router series, which can be used to generate default passwords. In case the implementation is not a shell script but needs to be compiled, README.md should be updated with compilation instructions instead of providing pre-built binaries.

Please ensure that all shell scripts are POSIX-compliant and licensed under the MIT License.
