Change requirement to be online for the magnetic-field-calculator

jonnymaserati opened this issue · 1 comments

Currently to add default data to the SurveyHeader class, the script needs to be run online for magnetic-field-calculator to lookup and fetch the data.

Change this to a try and default to some reasonable values if run offline.

Closed in #76 where libraries are only imported if they're available and where a None value can be passed with a reasonable default value.
