go get error (unrecongnized import path)

[hahwul]

Hi :D
As from the README, I tried to install through go get, but the following error occurs.

case1
OS: MacOS 10.15.5
Go version: go1.15 darwin/amd64

case2
OS: ubuntu 20.04
Go version: go1.13.8 linux/amd64

Same result

$ go get -u github.com/iamstoxe/urlgrab
package urlgrab/browser: unrecognized import path "urlgrab/browser": import path does not begin with hostname
package urlgrab/utilities: unrecognized import pat

Um, problem is using the local package. Is there any reason for configuring it locally?

	"urlgrab/browser"
	. "urlgrab/utilities"

an go build is same

$ go build

I modified it my way and built it. I've send the PR and I'll leave it to your judgment!
