binary detection: openbsd OpenSSH and portable OpenSSH

Hi,

(Not sure if i'm right here, because it's a contributor question and i'm not so familiar with go)

I would like to implement openbsd OpenSSH and portable OpenSSH binary detection with correct cpe's in one classifier.

So openbsd have two OpenSSH products with different cpe's:
- [normal](https://nvd.nist.gov/products/cpe/detail/DE876FD6-4D26-463F-886E-6A53DE98835B?namingFormat=2.3&orderBy=CPEURI&keyword=cpe%3A2.3%3Aa%3Aopenbsd%3Aopenssh&status=FINAL) `cpe:2.3:a:openbsd:openssh:9.6:-:*:*:*:*:*:*`
- [portable](https://nvd.nist.gov/products/cpe/detail/64848251-5FCD-476A-B2AB-744B23F6243F?namingFormat=2.3&orderBy=CPEURI&keyword=cpe%3A2.3%3Aa%3Aopenbsd%3Aopenssh&status=FINAL) `cpe:2.3:a:openbsd:openssh:9.6:p1:*:*:*:*:*:*`

I alrady have the regex to match the version `\x00OpenSSH_(?P[0-9]+\.[0-9]+)(p[0-9])?\x00` (is also match the optional portable `p1` information).

The question ist: how can I build this two different cpe in one classifier?
Is it possible to implement this with one classifier? If not I will make simply two classifyers: openssh-binary and openssh-portable-binary.

Thanks

The issue names no source file or test; start by locating Syft's binary-classifier entry point and comparing existing CPE handling. Use the supplied OpenSSH version regex and CPE examples as the expected inputs, with completion meaning normal and portable OpenSSH produce their respective CPEs.
