IGRF & dipole models are outdated

[gnadt]

IGRF v14 was released last year, which adds 5 years of coverage.

Thanks for letting me know. I will update the version here.

Done! I just tag a new release with IGRF v14 that is good up to 2030 (2035 considering reduces accuracy).

Super fast response, thanks! I'll note that the dipole model could also be updated (personally not useful to me, but this table was updated for IGRF v14). If you do make that change, couple other minor things are:

• Top of the readme still references IGRF v13
• IGRF v14 link(s) should probably go here instead

Just noting the igrf_coefficients.jl file still has a comment on line 25 indicating the coefficients come from IGRF 13. It's a small thing, but updating the comment will increase clarity.
