SYSML2 — Add standard domain libraries for mathematical and physical constants

There should be a Constants Domain Library that capture all mathematical and CODATA Fundamental Physical Constants as published on https://pml.nist.gov/cuu/Constants/, in particular from the ASCII list of all constants at https://pml.nist.gov/cuu/Constants/Table/allascii.txt. Each constant should include a specification of whether its real number value is exact or not and, if not, what the uncertainty is.

Defer

This issue requests additional functionality in the language beyond what was included as submitted. As such, it is out of scope for an FTF, and it is deferred for possible consideration by a future RTF.
