Updating the units database based on Resolution 1 of the 26th CGPM (2018), aka New SI.

Wikipedia for the info about the IEC standards (the actual standards are paywalled).

Todo:

[x] Find remaining 2014 CODATA constants in the file and get them updated to 2018.
[x] Find any remaining constants that used to be exact but aren't anymore.
[x] Fix parsec definition (not new SI, but might as well)
[x] Review changes to make sure they are correct
