CLI name is ambiguous, because both `cyclonedx-cli` and `cyclonedx` are used in document

Hi, I have a feedback.

I think the CLI name is ambiguous, because both cyclonedx-cli and cyclonedx are used in README.

cyclonedx-cli/README.md

Lines 56 to 57 in 5de8d19

	Usage:
	cyclonedx add files [options]

cyclonedx-cli/README.md

Line 73 in 5de8d19

`cyclonedx-cli add files --no-input --output-format json --exclude /.git/**`

So how about unifying the command name either cyclonedx-cli and cyclonedx in the document?

When we install the CLI with Homebrew, the command name is not cyclonedx-cli but cyclonedx,
so maybe cyclonedx is preferred.
