local repo added

[gespi1]

local repo struct

type Repo struct {
	Type string
	Path string
}

"local" repo works from a folder on the local FS, determined by the user specifies Path field in Repo Struct.

local repo doesnt cache on ~/.npc.
created func determineTemplateCache() that will set the template cache depending on the repo Type.

Optimally we should create an interface for Repo Struct ( the one in the repos dir ). We probably want all repo kinds to specify their Type It'll look like this for now:

type Repo interface {
	Type String
}

but idk how to best implement this 🫠

Yea for now it looks good to me. we can mess around with the structs in the future
