Generate filesystem based SBOM for miniconda dependency

[robdimsdale]

Summary

Add support for filesystem-based SBOM, in addition to the existing metadata-label-based BOM, in order to conform with: Paketo RFC0038.

Closes #173

Note: we also added CPEs for miniconda as that is a requirement of the upstream SBOM library.
