Explore nested GHA inputs

[bschilder]

As the rworkflows actions gets more comprehensive, the parameter list continue to grow. It might be better to nest these arguments in some way.

Ways to do this:

1. Create separate subactions that users can supply inputs to at each step. Break Actions report into steps #4
2. Nest inputs within the main rworkflow action: e.g.

in the workflow

 steps:
    - uses: neurogenomics/rworkflows@master
      with:
        run_bioccheck: ${{ false }}
           opt_1: ${{ false }}
           opt_2: 'myoption'

or maybe:

 steps:
    - uses: neurogenomics/rworkflows@master
      with:
        run_bioccheck.run: ${{ false }}
        run_bioccheck.opt_1: ${{ false }}
        run_bioccheck.opt_2: 'myoption'

in the action:

inputs.run_bioccheck.opt_2

Not sure if this syntax is supported by GHA though.
