Hi!

@cyclonedx/cyclonedx-library currently relies on optionalDependencies for some features. Because this mechanism is not really well-known (or even accessible), consumers end up with 10MB of additional dependencies.

My recommendation is to make these dependencies opt-in instead of opt-out:

• Move them to peerDependencies
• Mark them as optional with peerDependenciesMeta

Since this package is a software library not intended for standalone use, this would allow consumers to provide the required dependencies for the features they need.
