wmi_has_guid — check if a GUID is available 🎀

bool wmi_has_guid (const char *guid_string );

like, that's the whole thing. one argument, one bool back. no drama, no cap 💅

---

🦋 ARGUMENTS 🦋

• guid_string — a 36 char string, and it's gotta be in exactly this form: fa50ff2b-f2e8-45de-83fa-65417f2f49ba. 36 characters, hyphens in all the right places, main character formatting only 🔥

---

💖 DESCRIPTION 💖

so what she actually does: she checks if a given GUID is defined by _WDG. that's it. that's the whole job 🫶 lowkey the moment, but someone's gotta do it.
