Interfacer generates invalid code when package name contains hyphen

[paprikati]

We've tried to run interfacer against github.com/PagerDuty/go-pagerduty.Client.
When one of the function arguments is a package name, it generates:

	ListAuditRecordsPaginated(context.Context, pagerduty.ListAuditRecordsOptions, func(go-pagerduty.AuditRecord) bool) ([]pagerduty.AuditRecord, error)

however, go-pagerduty isn't a valid package name.
Would it be possible to pass args to tell interfacer which package name to use in this scenario?

I think interfaces should be smart enough to read the actual name of the package. Right now it does a dumb thing - it tries to infer the name from the (file-) import path.
