A number of specimen fields are empty

[jrdh]

Empty fields:

• DarTimeOfDay -> eventTime
• sumViceCounty -> viceCounty (another option for this is sumViceCountry and
  there's a spelling error in the actual EMu dumping? Either way, both options are
  empty).
• NesShape -> nestShape
• NesSite -> nestSite
• ColSiteDescription -> labelLocality
• MinAgeDataAge -> age
• MinAgeDataType -> ageType
• MinNhmTectonicProvinceLocal -> tectonicProvince
• MinNhmMiningDistrictLocal -> miningDistrict
• MinNhmRegionLocal -> geologyRegion
• MinMetPetType -> petrologyType

Need to see if there are other options for these, if not, might as well delete them from
the mapping.
