Support for specifying the output file name

[AnuradhaKaruppiah]

We have a need to provide requirements file as a part of each python package. We would like to generate it from a parent dependencies files that has multiple file keys. All of this is easily possible with this tool, only the name of the file is auto generated.

For example this snippet in dependencies.yaml files section -

  # morpheus-llm pip dependencies are published as a morpheus_llm package data file
  morpheus_llm:
    output: requirements
    requirements_dir: python/morpheus_llm/morpheus_llm
    includes:
      - morpheus_core_pip
      - morpheus_llm_pip

Generates python/morpheus_llm/morpheus_llm/requirements_morpheus_llm.txt. I would like to instead get python/morpheus_llm/morpheus_llm/requirements.txt. Can you please provide an option for output_file_name? And maybe add a sanity checker for dup file names?
