Add a way to specify the db file

[vdemeester]

In the case where I distribute the binary and the db file separately, I want to be able to specify where licenseclassifier should look for the db. This is related to go-licences (https://github.com/google/go-licenses/blob/master/licenses/classifier.go)

As of today, you need the source of the go-license binary in the right path (GOPATH, …) to be able to use it.

Another alternative would be to embedded the .db in the binary 👼

Hi @vdemeester,

I ran into this exact issue when trying to use go-licenses in a project with a custom GOPATH. I found out that this package already contains a way to adjust the Archive location using the OptionFn slice within the New() function call. https://github.com/google/licenseclassifier/blob/master/classifier.go#L89:L94

The issue is the go-licenses does not expose a way to call this from the command line. I opened a pull request (google/go-licenses#36) to fix that issue. If you are directly including the licenseclassifier module then you can do something similar to what I did in the PR.

Hope it helps.

Since this is an issue with the utility calling the classifier and not this code itself, closing the issue.
