Change uuid dependency to community maintained fork

[guywithacube]

github.com/gofrs/uuid is no longer being actively maintained
See satori/go.uuid#84 for more detail

---

The dependency satori/go.uuid causes the following:

$ go get github.com/ivanbeldad/kasa-go
go: github.com/ivanbeldad/kasa-go upgrade => v0.0.0-20191206080011-613ab073653e
go: finding module for package github.com/satori/go.uuid
go: found github.com/satori/go.uuid in github.com/satori/go.uuid v1.2.0
# github.com/ivanbeldad/kasa-go
/Users/guywithacube/go/pkg/mod/github.com/ivanbeldad/kasa-go@v0.0.0-20191206080011-613ab073653e/auth.go:32:12: assignment mismatch: 2 variables but uuid.NewV4 returns 1 values

Following the advice from satori/go.uuid#84, I think it would be wise to move towards an actively maintained fork.

Merged, thank you @guywithacube
