Add support for missing record types (supported in NSD)

[k0ekk0ek]

Originally simdzone started out as just a replacement zone parser in NSD. While it's become a project of it's own, we still want to replace NSD's current parser. Therefore, we must support at least all RRTYPEs supported by NSD.

RRTYPEs:

• PTR
• NXT (Add support for SIG and NXT RRs #104)
• KEY
• SIG (Add support for SIG and NXT RRs #104)
• SRV
• CERT (Add support for CERT RR #88)
• LOC (Add support for LOC RR #100)
• MD (easy)
• MF (easy)
• MB (easy)
• MG (easy)
• MR (easy)
• WKS (Add support for WKS RR #97)
• HINFO
• MINFO
• AFSDB
• RP
• X25
• ISDN
• RT
• NSAP (Add support for NSAP and NSAP-PTR RRs #89)
• NSAP_PTR (Add support for NSAP and NSAP-PTR RRs #89)
• PX (Add support for PX RR #90)
• GPOS (Add support for GPOS RR #101)
• EID (NOT a standard)
• NIMLOC (NOT a standard)
• NAPTR
• KX
• DNAME
• APL (Add support for APL RR #102)

• OPENPGPKEY (Add support for OPENPGPKEY RR #85)
• CSYNC (Add support for CSYNC RR #103)
• ZONEMD (Add support for ZONEMD RR #86)
• AVC

SVCB/HTTPS progress on #16.

With the addition of SVCB and HTTPs, simdzone now supports all RRTYPEs (plus extra) that NSD does. There's very likely still bugs, but we'll sort those out separately. Closing this issue.
