Question regarding correct behaviour for a domain with no TXT records

[ttacon]

When requesting the SPF records for a given domain that doesn't have any TXT records, I get back a PermError. Looking at the documentation for CheckIP (https://godoc.org/github.com/gopistolet/gospf#SPF.CheckIP) where the error codes are stated (albeit this documentation is for CheckIP and not New), I was wondering if when querying a domain that didn't have any TXT records it would be more appropriate, with respect to the RFC, to return None instead of PermError?

Thoughts?

Indeed the rfc says that a Permerror is something very serious. Not having a TXT record doesn't seem to be very serious to me :). Ill see if I can fix it, otherwise ill ask @DenBeke who wrote this package.

I'll look into #3 and #4 once I have a bit of time.
